symlinks to all of them.
this fixes kde/multimedia, which builds a libmpeg-0.3.0.so (using -release),
also known as libmpeg.so, and then links something with -lmpeg ...
(before this commit, we only had a symlink to the former)
it should really just use libmpeg.la instead, but let's have libtool handle
such attempts anyway.
might fix other stuff i'm not yet aware of, too.
we could not find /usr/X11R6/lib/libX11.la
therefore, parse -L arguments before everything else so we know in which
directories to search libraries.
fixes libcaca, and possibly others
