  New Revision: 63745

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=63745

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