If a IS_IN_* macro is defined, then NOT_IN_libc is always defined,
except obviously for IS_IN_libc. There's no need to check for both.

This patch fixes the remaining ONE_DIRECTION warnings for s390 specific conversions.
It defines ONE_DIRECTION to 0 like the patch from Steve Ellcey:
https://www.sourceware.org/ml/libc-alpha/2014-05/msg00039.html
Changelog:
* sysdeps/s390/s390-64/utf16-utf32-z9.c
(ONE_DIRECTION): Define.
* sysdeps/s390/s390-64/utf8-utf16-z9.c
(ONE_DIRECTION): Define.
* sysdeps/s390/s390-64/utf8-utf32-z9.c

This patch defines ELF_MACHINE_NO_RELA on all architectures. Tested
only on x86_64 to verify that the sources before and after are
identical except for two instructions that pass the current line
number in dl-machine.h to assert_fail.

preconfigure fragments.
This patch makes non-ex-ports architectures set base_machine and
machine based on the original configured machine value in preconfigure
fragments, like ex-ports architectures, rather than in the toplevel
configure.ac.
Tested x86 that the disassembly of installed shared libraries is
unchanged by the patch.
* configure.ac (base_machine): Do not set specially for particular
machines here.
* configure: Regenerated.
* sysdeps/powerpc/preconfigure: Move machine and base_machine
settings from configure.ac.

The glibc makefiles have a standard variable, $(rtld-prefix), to run
the dynamic linker with a default --library-path option; this is used
as the basis of lots of other variables for running programs compiled
with the newly built library.
A few places however use $(elf-objpfx)ld.so or
$(elf-objpfx)${rtld-installed-name} directly, with such a
--library-path option. This patch makes such places use
$(rtld-prefix) instead. I'm not aware of any significance in these
cases to the choice of ld.so or ${rtld-installed-name} when running
the dynamic linker, or to whether $(patsubst
%,:%,$(sysdep-library-path)) is included in the library-path as it is
in $(rtld-prefix) and just one of the places being changed.
Tested x86_64.
* elf/Makefile ($(objpfx)tst-unused-dep.out): Use $(rtld-prefix).
* iconvdata/Makefile ($(inst_gconvdir)/gconv-modules)

Various glibc build / install / test code has C locale settings that
are redundant with LC_ALL=C.
LC_ALL takes precedence over LANG, so anywhere that sets LC_ALL=C
(explicitly, or through it being in the default environment for
running tests) does not need to set LANG=C. LC_ALL=C also takes
precedence over LANGUAGE, since
2001-01-02 Ulrich Drepper <drepper@redhat.com>
* intl/dcigettext.c (guess_category_value): Rewrite so that LANGUAGE
value is ignored if the selected locale is the C locale.
* intl/tst-gettext.c: Set locale for above change.
* intl/tst-translit.c: Likewise.
and so settings of LANGUAGE=C are also redundant when LC_ALL=C is
set. One test also had LC_ALL=C in its -ENV setting, although it's
part of the default environment used for tests.
This patch removes the redundant settings. It removes a suggestion in
install.texi of setting LANGUAGE=C LC_ALL=C for "make install"; the
Makefile.in target "install" already sets LC_ALL_C so there's no need
for the user to set it (and nor should there be any need for the user
to set it).
If some build machine tool used by "make install" uses a version of
libintl predating that 2001 change, and the user has LANGUAGE set, the
removal of LANGUAGE=C from the Makefile.in "install" rule could in
principle affect the user's installation. However, I don't think we
need to be concerned about pre-2001 build tools.
Tested x86_64.

As previously noted
<https://sourceware.org/ml/libc-alpha/2013-05/msg00696.html>,
$(elf-objpfx) and $(elfobjdir) are redundant and should be
consolidated. This patch consolidates on $(elf-objpfx) (for
consistency with $(csu-objpfx)), also changing direct uses of
$(common-objpfx)elf/ to use $(elf-objpfx).
Tested x86_64, including that installed shared libraries are unchanged
by the patch.
* Makeconfig [$(build-hardcoded-path-in-tests) = yes]
(rtld-tests-LDFLAGS): Use $(elf-objpfx) instead of
$(common-objpfx)elf/.

Added support for TX lock elision of pthread mutexes on s390 and
s390x. This may improve lock scaling of existing programs on TX
capable systems. The lock elision code is only built with
--enable-lock-elision=yes and then requires a GCC version supporting
the TX builtins. With lock elision default mutexes are elided via
__builtin_tbegin, if the cpu supports transactions. By default lock
elision is not enabled and the elision code is not built.

As recently discussed
<https://sourceware.org/ml/libc-alpha/2014-02/msg00670.html>, it
doesn't seem particularly useful for libm-test-ulps files to contain
huge amounts of data on ulps for individual tests; just the global
maximum observed ulps for each function, together with the
verification of exceptions, errno and special results such as
infinities and NaNs for each test, suffices to verify that a
function's behavior on the given test inputs is within the expected
accuracy. Removing this data reduces source tree churn caused by
updates to these files when libm tests are added, and reduces the
frequency with which testsuite additions actually need libm-test-ulps
changes at all.
Accordingly, this patch removes that data, so that individual tests
get checked against the global bounds for the given function and only
generate an error if those are exceeded. Tested x86_64 (including
verifying that if an ulps value is artificially reduced, the tests do
indeed fail as they should and "make regen-ulps" generates the
expected changes).

Extend the range of numbers handled via unsafe mode.
Add expl testcase and regenerate ULPs for s390.

See commit 41b1792698a335d3a85381921a84a16e9635f36a for testcase.
Note: while this works on s390x, the s390 code hangs when using -e.
But it hangs regardless of this code (the hang seems to occur before
the exit func is even called). I didn't look too closely at it as
it seems to be an issue external to this file, so this code shouldn't
make the situation any worse.

Autoconf has been deprecating configure.in for quite a long time.

The pointer guard used for pointer mangling was not initialized for
static applications resulting in the security feature being disabled.
The pointer guard is now correctly initialized to a random value for
static applications. Existing static applications need to be
recompiled to take advantage of the fix.
The test tst-ptrguard1-static and tst-ptrguard1 add regression
coverage to ensure the pointer guards are sufficiently random
and initialized to a default value.

Resolves: #15465
The program name may be unavailable if the user application tampers
with argc and argv[]. Some parts of the dynamic linker caters for
this while others don't, so this patch consolidates the check and
fallback into a single macro and updates all users.

The s390 and s390x sysdep.h files include the more generic sysdep.h.
The more generic sysdep.h defines PSEUDO. This causes an annoying
CPP warning saying the PSEUDO was redefined. This patch removes the
warning by undefining PSEUDO before the redefinition. This is in line
with what all the other machines do.

* sysdeps/s390/s390-32/sysdep.h: Undefine PSEUDO before redefinition.
