libmad and pkgconfig

Hi!

I've sent this email today without subscribing first. It seems like it di=
dn't reached list. So I subscribed and sent it again.

Recently I packaged mpd for NixOS [1] and found one problem. mpd's config=
ure uses pkgconfig to find libmad. There was no mad.pc in NixOS and I was=
 surprised to find that Arch Linux, Gentoo and Debian patch libmad to ins=
tall mad.pc. So I took patch from Arch Linux [2]. I think it would be goo=
d to add this patch to libmad sources, what do you think?
