mjit.c: set PIC flags on clang for FreeBSD and glibc

Browse source 
This seems required on FreeBSD 11.1 (clang 4.0.0) and
Debian stretch (clang 3.8.1) for shared libraries.

Note: Not checking __linux__ because there are statically-linked
Linux distros (I don't know if they can support MJIT).  But
glibc doesn't support static linking, so we guard on that.

Maybe other platforms will need this, too.
