maint: suppress gcc's new -Wcast-function-type in gnulib
* configure.ac (WERROR_CFLAGS): Suppress gcc's new -Wcast-function-type
warning in gnulib, because it would trigger on this:
sig-handler.h:47:12: error: cast between incompatible function types\
from 'void (* const)(int, siginfo_t *, void *)' \
{aka 'void (* const)(int, struct <anonymous> *, void *)'} \
to 'void (*)(int)' [-Werror=cast-function-type]
return (sa_handler_t) a->sa_sigaction;
