Again, I don't agree here (backed by p2): The package is wrong if it
asserts that it's "Architecture: all". It contains powerpc specific
stuff and can only be built on (i.e. for) that architecture. Therefore,
it should be "Architecture: powerpc".

Workarounds like an error on wrong toolchain architecture are wrong
(there is an error anyway if you try to build on !powerpc).

Thanks for considering.
