`autoconf -Wall` notes that AM_PROG_CC_STDC is obsolete:
Fixes this autoconf warning:
configure.ac:40: warning: 'AM_PROG_CC_STDC': this macro is obsolete.
configure.ac:40: You should simply use the 'AC_PROG_CC' macro instead.
configure.ac:40: Also, your code should no longer depend upon 'am_cv_prog_cc_stdc',
configure.ac:40: but upon 'ac_cv_prog_cc_stdc'.
aclocal.m4:770: AM_PROG_CC_STDC is expanded from...
configure.ac:40: the top level
Since we build with a C++ compiler now, I don't think this is relevant.
If you look at the messages removed from gdbsupport/aclocal.m4, it says
that this functionality is now integrated in AC_PROG_CC, which we
already call. So it might not even make a difference.
We had a local version of AM_PROG_CC_STDC, in gdb/acinclude.m4 (only
used by gdb/configure.ac), remove it.
gdb/ChangeLog:
* acinclude.m4 (AM_PROG_CC_STDC): Remove.
* configure: Re-generate.
* configure.ac: Remove AM_PROG_CC_STDC.
gdbsupport/ChangeLog:
* aclocal.m4: Re-generate.
* configure: Re-generate.
* configure.ac: Remove AM_PROG_CC_STDC.

This moves many needed configure checks from gdb and gdbserver into
common.m4. This helps gdbsupport, nat, and target be self-contained.
The result is a bit spaghetti-ish, because gdbsupport uses another m4
file from gdb/. The resulting code is somewhat non-obvious. However,
these problems already exist, so it's not really that much worse than
what is already done.

This patch moves the gdbsupport directory to the top level. This is
the next step in the ongoing project to move gdbserver to the top
level.
The bulk of this patch was created by "git mv gdb/gdbsupport gdbsupport".
This patch then adds a build system to gdbsupport and wires it into
the top level. Then it changes gdb to use the top-level build.
gdbserver, on the other hand, is not yet changed. It still does its
own build of gdbsupport.
