[RFC] [PATCH] PPC32 R2 thread register support

Hi,

this patch adds simple (no __thread, no TLS) thread register support to glibc. 
It's been running for over a month now here without a single problem.

I've flagged it RFC, cause I want to make sure this doesn't ABI conflict with 
any __thread or TLS work-in-progress.

Franz.
