libmad: remove
This is largely equivalent to the recipe in OE-Core apart from LICENSE_FLAGS, insignificant patch differences, and an additional patch for avr32 optimisation (and since there appears to be no public layer for an avr32 machine, there's not a great deal of point in preserving the latter).

1Here is a patch for adding pkg-config support to libmad.
2It would make life a bit easier for distro maintainers if this was applied.
3In case you didn't know, pkg-config is a tool for providing LDFLAGS and
4CFLAGS for packages using shared libraries. It's on freedesktop.org.
5Debian has already been distributing the pkg-config file mad.pc with
6libmad for some time, and people developing on debian (notably xmms2
7developers) have started relying on this support being present, causing
8some confusion for people installing from source and on some BSDs which
9do not provide mad.pc (google: pkgconfig libmad).
