I suspect we'll just have to be careful never to add an "eb" override,
in much the same way as a 64 override would also cause problems for
x86_64. There is code in place to change the _ to - for package feed
use.

Longer term I'd like to see us find a better character for overrides
than the current use of "_" but that would be a fair bit of work to
achieve. I'd like to think that would performance as well as readablity
of .bb files but I've yet to prove it.
