Asked google and it found following page:
http://www.kernel.org/pub/tools/crosstool/
Architecuter OK? gcc version
---------------------------------
alpha No gcc 4.0.2
arm Yes gcc 3.4.5
ia64 Yes gcc 3.4.5
m68k Yes gcc 3.4.5
mips Yes gcc 3.4.5
sh4 Yes gcc 3.4.5
sparc Yes gcc 3.4.5
sparc64 Yes gcc 3.4.5
x86_64 Yes gcc 3.4.5
So from this list of tool chains we can continue to do cross builds
of all except alpha.
But the gcc version is getting ancient..
Why it shall be so hard to do cross build toolchains is above my
imagination but then I also never looked at what it involes.
Added Vegard that maintain these pages.
