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).

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