Right, but they're still valid platforms that exist in the wild. We
already support (for example) installation on Bay Trail based machines
that use ia32 UEFI.

UEFI is more common on arm64, but there are some 32-bit ARM machines
that will boot with UEFI, and probably more coming. We've just turned
on more UEFI support in the armmp kernels for this reason.

It's problematic, but it exists and is growing in usage - we can't
just ignore it.

I don't see the problem - just build the appropriate binaries for each
of the architectures natively. Am I missing something?
