"System libraries" are auto-detected.
(vda is currently wrong, I forgot to
work on this in the last days...)
Obviously you can discuss what is a system library
and what is not a system library, we so far argued
that not only libz and libbz2 (and libva) but alsa
and sdl are also system libs.
I find this argumentation not unreasonable and I
do not remember a user or a packager complaining.
(But when we broke libva, complaints were made
(Please understand that this is *our* definition
of "system library", it may of course diverge -
significantly - from other people's definition.)

Then please make xv autodetected.
