Yes, you're right.  But it seems as though _append overrides do work
(see my other mail to Bernhard Reutner-Fischer), and I don't think the
bitbake documentation notes that underscores are prohibited in
OVERRIDES.  So I think this is a bug in bitbake and should be fixed
there.

Changing the architecture to x86-64 would be a possibility, but clearly
there are already folks using x86_64 (since there are files in site/
with that naming, for example) so this seems like it would be best
avoided.  Also it would require a tmpdir version bump to take care of
BUILD_SYS for all the people who are cross compiling from x86_64, and
that also seems like something best avoided if possible.
