[kaffe] Kaffe on XScale

[Jari Korva]

Hi,

there was an additional f0 lurking (see below). Because my Assembly is
pretty bad, I just removed it blindly - but it made Kaffe to compile!

The resulting Kaffe does not quite work though (throws an NPE in
System.initProperties, see bottom of this message).

Cheers,
  Jari
