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...
