Make linknamespace tests check only relevant libraries.
This patch addresses one known caveat in the linknamespace tests: with
this patch they will now only look for definitions of symbols in
relevant libraries, meaning that librt and libpthread are not checked
for ISO C standards, XPG3 and XPG4.
In particular, this means that if __pthread_initialize_minimal is
somehow brought in for one of those standards, the definition from
libc-tls.o will be considered instead of that from libpthread, so
avoiding bringing in lots of other libpthread symbols. This should
address some of the failures reported by Carlos in
<https://sourceware.org/ml/libc-alpha/2014-11/msg00882.html>, where
__pointer_chk_guard_local brought in __pthread_initialize_minimal.
Tested for x86_64. The removal of one XFAIL for XPG4 actually shows
up a header bug (shm_open should not be declared for XPG4 - the
namespace issue was for symbols brought in by shm_open, which is no
longer found at all now librt isn't searched; I've filed bug 17663 for
the header bug, though it would show up eventually anyway in the
course of review of conform/ data against XPG4).
Committed.

variable.

(tests-special): Append $(linknamespace-symlist-stdlibs-tests)
instead of $(objpfx)symlist-stdlibs.
(linknamespace-libs-isoc): New variable.
(linknamespace-libs): Use $(linknamespace-libs-isoc).
(linknamespace-libs-ISO): New variable.

($(objpfx)symlist-stdlibs): Replace by
$(linknamespace-symlist-stdlibs-tests). Use
$(linknamespace-libs-$*) as set of libraries.

definitions of symbols from irrelevant libraries.
