target/89125 - BSD and math functions
Back story: When GCC is configured and built on non-glibc platforms,
it seems very little to no effort is made to enumerate the available
C99 libm functions. It is all or nothing for C99 libm. The patch
introduces a new function, used on only FreeBSD, to inform gcc that
it has C99 libm functions (minus a few which clearly GCC does not check
nor test).

PR target/89125
* config/freebsd.h: Define TARGET_LIBC_HAS_FUNCTION to be
bsd_libc_has_function.
* targhooks.cc (bsd_libc_has_function): New function.
Expand the supported math functions to inclue C99 libm.
* targhooks.h (bsd_libc_has_function): New Prototype.
