The last universal Mac builds for libdiscid were quite tedious:
building for 32 bit, for 64 bit, moving the libs somewhere, use lipo.
Generating 32 bit also needs additional flags, since we don't have a real 32 bit machine.

Anyways, that should become easier.
Perfect would be when make dist would already build binaries on Mac and Windows.

Though Windows builds are not that painful. We only have to make sure we include the current source, a README and rename to discid.dll (wich is the "official" name).
