I am trying to figure out now what it takes to build GHC using the LLVM
backed on 32-bit PowerPC but it currently doesn't seem to be supported.

I am not sure what needs to be patched to enable LLVM code generation
for this target, but we will most likely need at least modify the script
utils/llvm-targets/gen-data-layout.sh and probably a little more.

If enabling LLVM support for a given target is not too involved, we could
also look into enabling it for loong64, m68k and sparc64 which also have
LLVM backends although the one for m68k is still in development.
