eglibc and fun with config.sub

Sounds good to me FWIW.  Just one comment...

I'm taking you literally here, but I think you want things like
armeb-linux-gnueabi to be treated like arm-linux-gnueabi.

TBH, I think unconditionally using the autodetect (but setting $machine
rather than $submachine, as you say) would be easier and more consistent
across packages.  gcc and eglibc will then agree on the target, whereas
the extra complication in the current scheme is there simply to make
eglibc and gcc disagree in certain cases.  But I realise we might not
want to fight that fight.
