Nope, it's not cruft, AFAICS.  The point is that installed libtool
libraries (created with, say, older libtool versions) may contain the
`-lc' in dependency_libs, and there we filter those out.  Surely we may
be able to unify both of these crufts, or really fix by adding another
tag variable.  But for now I'll just duplicate the test and appl..
