this isn't particularly helpful if you just try to build upstream GCC
for comparision with your own targets or to verify a patch of yours.
Having to go hunting for configs like this if you're not a regular
FreeBSD user is a no-no IMO.  GCC trunk should either build out of the
box or the quirks be documented in install.texi.  Otherwise, non-FreeBSD
developers will get frustrated and give up on the target, to the
detriment both of their patches and the platform.

Unfortunately, it's pretty common that targets keep necessary patches in
some ports collection of their own (usually a different one per target)
and neglect to submit them upstream.
