The switch to linking with libtool now shows a very long link line
even when V=0. This patch arranges to silence libtool in this
situation.

Use GDB's silent-rules.mk to make some rules silent by default. These
rules cover most of what is built in sim/.
gdb/ChangeLog:
* silent-rules.mk (ECHO_CCLD, ECHO_AR, ECHO_RANLIB): New.
sim/ChangeLog:
* common/Make-common.in (COMPILE, libsim.a, run$(EXEEXT),
gentmap.o, gentmap): Make rules silent.

This applies the silent-rules.mk treatment to gdb/testsuite/Makefile.
gdb/ChangeLog
2021-06-01 Tom Tromey <tromey@adacore.com>
* silent-rules.mk (ECHO_CC): New variable.
gdb/testsuite/ChangeLog
2021-06-01 Tom Tromey <tromey@adacore.com>
* Makefile.in (all): Don't print anything.
($(abs_builddir)/site.exp site.exp): Use $(ECHO_GEN).
(expect-read1): Likewise.
(read1.so): Use $(ECHO_CC).
Include silent-rules.mk.

I would like to modify how the init.c file is generated (its content).
But as it is, a shell script with multiple sed invocations in a Makefile
target, it's not very maintainable. Replace that with a shell script
that does the same, but in a more readable way.
The Makefile rule uses the "-" prefix in front of the for loop, I
presume to ignore any error coming from the fact that xml-builtin.c and
cp-name-parser.c are not found in the srcdir (they are generated source
files). I prefer not to blindly ignore errors, so filter these files
out of INIT_FILES instead (we already filter out other files).
There are no expected meaningful changes to the generated init.c file.
Just the _initialize_all_file declaration that is moved down and "void"
in parenthesis that is removed.
The new regular expression is a bit tighter than the existing one, it
requires the init function to be followed by exactly ` ()`. Update
bpf-tdep.c accordingly.
gdb/ChangeLog:
* Makefile.in (INIT_FILES_FILTER_OUT): New.
(INIT_FILES): Use INIT_FILES_FILTER_OUT.
(stamp-init): Use make-init-c.
* bpf-tdep.c (_initialize_bpf_tdep): Remove "void".
* silent-rules.mk (ECHO_INIT_C): Change.
* make-init-c: New file.

This minimizes the "make" output from the yacc and lex rules,
following the same technique as the rest of the Makefile.
The lex rule had a special case to deal with the situation where flex
is not available. I don't think this is needed, so I removed it. If
flex is truly unavailable, the person building gdb can simply "touch"
the output file.
gdb/ChangeLog
2018-07-09 Tom Tromey <tom@tromey.com>
* Makefile.in (%.c: %.y): Use ECHO_YACC.
(%.c: %.l): Use ECHO_LEX. Just fail if flex not available.
* silent-rules.mk (ECHO_YACC, ECHO_LEX): New variables.

macOS requires that the gdb executable be signed in order to be able
to successfully use ptrace. This must be done after each link.
This patch adds a new --enable-codesign configure option so that this
step can be automated.
gdb/ChangeLog
2018-06-28 Tom Tromey <tom@tromey.com>
* NEWS: Mention --enable-codesign.
* silent-rules.mk (ECHO_SIGN): New variable.
* configure.ac: Add --enable-codesign.
* configure: Rebuild.
* Makefile.in (CODESIGN, CODESIGN_CERT): New variables.
(gdb$(EXEEXT)): Optionally invoke codesign.

Many projects (e.g. the Linux kernel) and build systems use "silent"
rules, which means that they'll only print a summary of what's being
done instead of printing all the detailed command lines. While chatting
on the #gdb IRC channel, I realized a few people (including me) thought
it would be nice to have it in GDB too.
The idea is that too much text is not useful, the important information
gets lost. If there's only the essential information, it's more likely
to be useful. Most of the time, when I look at the build output, it's
to see how it's progressing. By just printing a brief summary of each
operation, I can easily spot what's currently being compiled and
therefore how the build progresses (with time you know the order in
which files are compiled almost by heart).
As with other projects (Linux, automake-based things, probably others),
it's possible to print the complete command lines by passing V=1 to make
(or any other non-zero value).
I had one hesitation about this: when people report build failures, we
are more likely to miss the full compile command line. We'll probably
sometimes need to ask people to include the build log with "make V=1".
I don't think it's a big downside, if other projects the size of the
Linux kernel can live with it, I'm sure we can too.
