Fortunately I was able to get set up with buildroot and a simulator, so
it was possible for me to test booting a Linux kernel. I've tried
building the toolchain on a 32- and 64-bit system, and using both for
building the kernel resulted in something that would boot up and
appeared to function normally.

A revised series of patches (that fixes the failed check on 32-bit
systems that was present in the first series of patches) is at:

Best regards,
Graham.
