I'm also using x86_64 with cross-compiler:

This assembler was configured for a target of `powerpc-elf'.
Using built-in specs.
Configured with: ../configure --target=powerpc-elf --disable-nls
--disable-threads --enable-languages=c --disable-shared
Thread model: single
gcc version 4.2.4

This GDB was configured as "--host=x86_64-unknown-linux-gnu
Configuring for *-elf is easier than *-linux, because then the include
files, libgcc, crt0.o etc. will not be needed. These can be difficult
to compile sometimes. The drawback is that you can't use the compiler
for normal Unix programs, only for OpenBIOS and maybe Linux kernel.
BTW, there is a bug in one of the tools (binutils, gcc, gdb, can't
remember which): if you want the tool for powerpc64, the only
supported target is powerpc64-linux, powerpc64-elf won't work. This is
not a problem for OpenBIOS because the same binary can be used for
both 32 and 64 bit CPUs.
