Currently NetBSD/powerpc uses a.out format for nearly everything.  The only
exception is the boot-code that is in ELF format with a special note-section
to conform to the format that PReP and PPCP mandate for booting.

To allow the generation of the proper gcc, I've made the diffs for gcc 2.7.2.1
available in ftp://ftp.NetBSD.ORG/pub/NetBSD/arch/powerpc/gcc/gcc.diffs.gz.
You'll have to configure --target=powerpc-aout-netbsd after applying these
diffs.

Note that this is only the compiler.  Proper binutils are needed in addition
to that to make a cross development environment.  I'm using a specially hacked
version of the NetBSD assembler and linker, so that isn't easy to make available
to others for cross-compilation.  So sorry :-(, currently you are on your own
on that.
