Interesting, I'll have to have a try... I thought you required a
gcc with thread support to build glibc w nptl...

It should be, the kernel is self contained, by rights it shouldn't need
anything else

One interesting bug I've noticed so far with sysroot and mips, cross
building flex barfs out with a sys-rooted cross-toolchain due to x86
assembler being passed to gas if any optimisation is set
(assembler generated is fine without optimisation)

Funnily enough this behaviour does not occur with a non-sysrooted
cross-toolchain... still looking into what triggers this...
