* gthr-posix.h (__gthread_active_p): Use the Solaris implementation

for FreeBSD as well.

This is the fix for __gthread_active_p() returning false positives
which was committed as rev. 1.1.1.8.2.1 to RELENG_7 but now looped
back to the vendor branch via the GCC repository and relicensed to
be GPLv2 by me.
Thanks go to gerald@ for getting the fix approved upstream and for
committing to the GCC repository.

working interface is always exposed. On FreeBSD 6 and later, libc also
exposes a dummy POSIX threads interface, similar to what Solaris 2.6 up
to 9 does. FreeBSD >= 700014 even provides a pthread_cancel stub in libc,
