Changes since 1.4: +14 -1 lines

Hardcode a workaround for perl's DynaLoader.a which is definitely a
PIC code archive, but libtool isn't smart enough to realize it.  Munge
the name within cmd-sink-libtool into something that will make libtool
recognize it as a PIC code archive.  We unmunge it in arg-pp-main so
non-libtool wrappers see the right thing.  This let's us use libtool
to link applications with an embedded Perl interpreter.

I feel so dirty...
