commit 6707f161cab0f46a429a8002413a6e39846eff5e
Author: Ronald G. Minnich

Extend xcompile support for strange names

Some compilers report littlearm instead of arm. But the compiler names
    itself arm. Recognize this strange convention and do the right thing.
    Note we assume "littlearm" and "arm" are the same -- a safe assumption.
    If we can find the person who runs ARM in big-endian mode someday,
    we can ask them why.
