Fun fact: we cause configure to fail for OS X <= 10.4 anyway:
https://github.com/open-mpi/ompi/blob/master/configure.ac#L328-L347
According to the comment, we do this because of a known-bad implementation of
pty in the OS X kernel that causes kernel panics.
So I think we're definitely safe removing a OS X 10.4.x workaround.
