If long double math functions do not work, drop uselongdouble.
This moves a earlier version of the test from the freebsd hints
to Configure, thus stopping also any other platforms that have
lacking longdouble implementations.
The test is not comprehensive (not all long double interfaces are tested),
but it covers some of the most common ones.
The earlier test was actually wrong, so no FreeBSD could ever pass.
Sorry, FreeBSD.
