By the way, if this ever _does_ start to work, I'd appreciate hearing about
it.
Right now, my build scripts are building a PowerPC kernel and ext2 filesystem
image, using a procedure that works on arm, mips, x86, and x86-64. It's
producing a _result_, but I have no idea if it actually works. I do know
that I can't run it under qemu the way I can all the others. (Even sparc at
least _boots_, I think its problem is a uClibc issue.)

Shell scripts to build all that from source (plus cross compilers and a
tarball of the files in the ext2 image) are one level up.

Well, it's certainly inconvenient. The custom kernel I can do, the filesystem
I've got. But bootloaders are a bit of a weak spot with me...
