icedtea6 build failures on alpha and armel using gcj

[Matthias Klose]

Building icedtea6 on alpha and armel using a two stage bootstrap fails with 
different errors. These are no new errors, just rechecked the two stage 
bootstrap, because the one stage build fails to build cacao after the b18 
update. On alpha:

I vaguely remember we had a patch in the past to back out some of the constants 
stuff.


On armel:
