Avoid compiler complaints from Transmeta Crusoe detection on x86 builds

Multi-character character constants are implementation defined, and
while it MAY be reliable enough on i386 gcc, even that produces a
warning. I don't have a test-Robinson here so rather than risk a
conversion to string comparison like the other is_arch() tests are,
just write out the integer and leave the character constant as a
reference comment.
