HI, openbios guys,

Today i compiled openbios on my ppc64 box, encoutered some questions:

[root@945n03 openbios]# ./config/scripts/switch-arch ppc
Configuring OpenBIOS on ppc64 for ppc
ERROR: no powerpc cross-compiler found !

When i run "setarch 32 bash", "switch-arch" can work well, but it
fails to run "make"

Who can give me some advices?
