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`.
