Well, I was actually looking for some review on those combinations. In
short:

 * There should not be any change for uClibc itself (0.9.33, special
   ARC and Xtensa version, snapshot)

 * For uClibc-ng, the change should be that NPTL becomes the only
   available option, unless you're on ARC, Blackfin or i386 (and by
   i386, I really mean only i386: NPTL on >= i486 is fine).

Sure, I'll fix that up. But I'd prefer to have a review on the
combinations.

Thanks,

Thomas
