USE_DEV_PTMX should get defined on FreeBSD. That define is just wrapping
up several tests. The branch guarded by USE_DEV_PTMX also requires other
functions like grantpt() so tests for those should continue to be
honoured even when we have posix_openpt().

With earlier versions of zsh and recent FreeBSD, it was necessary to use
"kldload pty" for zpty to work. That brings /dev/ptmx into existance. It
seems the configure tests are effectively still requiring that. I think
the approach in the following patch should work but I now need to find a
FreeBSD machine with the pty module unloaded to test it.

Is the -o option to test safe to use in configure? It seems existing
tests use || and && but the precedence of those wouldn't be right.
