Simon Marchi b318629fe7 gnulib: update to bd11400942d6 
Update the gnulib import to fixes these issues:

  - GDB build with clang + glibc < 2.33.

      https://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=d6a07b4dc21b3118727743142c678858df442853
      https://lists.gnu.org/archive/html/bug-gnulib/2022-04/msg00072.html

    With glibc < 2.33, gnulib (since relatively recently) enables a
    replacement for free (see gnulib/import/m4/free.m4).  In that path,
    clang shows this error:

        make[2]: Entering directory '/home/smarchi/build/binutils-gdb-clang/gdbsupport'

        ^

    The gnulib commit mentioned fixes the exception specification of `free`.

Suppress extern inline with HP-UX cc, as it appears to be broken; see
<https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
Suppress extern inline with Sun C in standards-conformance mode, as it
mishandles inline functions that call each other. E.g., for 'inline void f
(void) { } inline void g (void) { f (); }', c99 incorrectly complains
'reference to static identifier "f" in extern inline function'.
This bug was observed with Oracle Developer Studio 12.6
(Sun C 5.15 SunOS_sparc 2017/05/30).
Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
on configurations that mistakenly use 'static inline' to implement
functions or macros in standard C headers like <ctype.h>. For example,
if isdigit is mistakenly implemented via a static inline function,
a program containing an extern inline function that calls isdigit
may not work since the C standard prohibits extern inline functions
from calling static functions (ISO C 99 section 6.7.4.(3).
This bug is known to occur on:
OS X 10.8 and earlier; see:
https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
DragonFly; see
http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log
FreeBSD; see:
https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
Assume DragonFly and FreeBSD will be similar.
GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
inline semantics, unless -fgnu89-inline is used. It defines a macro
__GNUC_STDC_INLINE__ to indicate this situation or a macro
__GNUC_GNU_INLINE__ to indicate the opposite situation.
GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
semantics but warns, unless -fgnu89-inline is used:
warning: C99 inline functions are not supported; using GNU89
warning: to disable this warning use -fgnu89-inline or the gnu_inline function attribute
It defines a macro __GNUC_GNU_INLINE__ to indicate this situation.

section 2.4.3. Note that malloc(), sprintf(), and fwrite(), in
particular, are NOT async-signal-safe.
* All memory locations (variables and struct fields) that these functions
access must be marked 'volatile'. This holds for both read and write
accesses. Otherwise the compiler might optimize away stores to and
reads from such locations that occur in the program, depending on its
data flow analysis. For example, when the program contains a loop
that is intended to inspect a variable set from within a signal handler
while (!signal_occurred)
;
the compiler is allowed to transform this into an endless loop if the
variable 'signal_occurred' is not declared 'volatile'.
Additionally, recall that:
* A signal handler should not modify errno (except if it is a handler
for a fatal signal and ends by raising the same signal again, thus
provoking the termination of the process). If it invokes a function
that may clobber errno, it needs to save and restore the value of
errno. */
