ppu-gcc error while cross-compiling kernel on x86

[Aaron Brice]

Binary package hint: ppu-gcc

Trying to cross-compile latest ubuntu-hardy kernel from git, commit 45a2f1fa59db5a20f63cd3f120cf5df5f51d0e0b fails with internal compiler error.

Running on x86 32 bit, compiling for ps3

If you try to reproduce, the Makefile in that commit has a bug that prevents cross-compiling powerpc or ia64:

CC = $(CROSS_COMPILE)gcc

#
# gcc-4.2 won't build powerpc64-smp or ia64.
#
ifneq (,$(findstring $(ARCH), powerpc ia64))
CC = gcc-4.1
endif

I just deleted the second part of that.
