Improve AC_SYS_YEAR2038_RECOMMENDED diagnostic
* lib/autoconf/specific.m4 (AC_SYS_YEAR2038_RECOMMENDED):
Do not recommend gcc -m64, as that likely will not work.
Problem reported by Bruno Haible in:
https://lists.gnu.org/r/bug-gnulib/2023-05/msg00060.html
Instead, mention that 32-bit time_t is not recommended
for this package, before telling the builder how
to configure with 32-bit time_t anyway.
