Enforce linkage with pthread library on OpenBSD
This patch enforces linkage with pthread library on OpenBSD. This is
done in order to avoid linker errors when linking with libffi which
requires POSIX threading but itself is not linked with libpthread
directly. So client binaries (of libffi) needs to link against
libpthread explicitly
