Hi Josh,

Excerpts from Josh Boyer's message of Fri Oct 01 21:36:35 +1000 2010:

As I said the kernel can be built today with an unpatched toolchain
targetted at powerpcle-elf, the new powerpcle-linux target is mainly
required for userspace, but yes I want to get those patches out as soon
as possible.

As Ben said this was for a proof of concept and changing uClibc to
support it was quite literally a one line change.

I've been using stable packages as my base on the toolchain side of
things (gcc 4.4.4, binutils 2.20.1 and uClibc 0.9.31) so uClibc is still
using linuxthreads since they haven't released a version with NPTL yet.

Good point.
