I do care. For example, imagine somebody wanting to support an
enterprise distro on both BG/Q and some FSL based HW ...

Besides, this has generally forced us to do things more cleanly and I
don't want to go back into #ifdef land. These cores are both arch 2.06 E
compilant, there is no good reason to prevent or forbid having them
build into a single binary image.

Look at the mess ARM got into and the pain they are having getting out
of with that stuff ... No way I'm going backward with split configs. If
anything, I'd like to reconcile things even more.

Cheers,
Ben.
