At issue is that CONFIG_MACH_TYPE (which will require a little thinking
about how to migrate) is not something that can be up and removed.  We
support booting old Linux and we support booting non-Linux OSes that
also make use of the old bd struct.

Something I had done half an experiment on at some point, and forgotten
about, was syncing only the MACH_TYPE_xxx values as the entire rest of
the header contains logic we don't need.  I'll give that a whirl and
report back.
