Subject: drop (broken) support for Alpha, PPC, Sparc & most of IA64

Including Xsun, silo & yaboot support

Rationale: it's unused/unmaintained for years and those arches are beyond
any hope of being usefull any day...
They just got in the way...

Part of IA64 support is still kept (eg: support for GPT, EFI, right xorg
driver at install, ...) as it might be usefull to extend to other arches

Next to consider: Xbox?
