grr, spu-gcc is a bad alias for spu-elf-gcc even worse ppu-${something}
is a quick hack from the start, you should expect to have embedspu from
the current local/cross toolchain (that is either plain embedspu or the
same prefix you have in the compiler).

Since they won't be out of business soon, you may iterate across spu-
spu-elf- and probably soon gcc -mspu to check for an spu compatible
compiler (xlc should be treated on a later time IMHO)

same for embedspu with "", ppu-, ${_cc//gcc}

or something similar/smarter.
