Because this wheel has already been re-invented many times, and usually
it's much simpler than libtool, so we don't have to re-invent it
anyways.

:)

Eventually though, Linux-PAM may come to be used on so many platforms
that libtool becomes inevitable.

Well, yes, as long as the compiler link command line doesn't vary too
much from GCC to SUNWspro (it shouldn't).
