That's no problem, I've created an overlay and using CVS HEAD
binutils/gcc/glibc.  AFAIK it's the only place with everything in.  I'm
emerging it all myself.


Seems glibc doesn't want to enable nptl for plain arm-* which it has wrongly
determined I'm using... I am using --with-cpu=iwmmxt --with-arch=iwmmxt
--with-abi=iwmmxt, it is of armv5e compatible.
