CVS binutils has the necessary TLS support.

Alan Modra (cc'd) has been working on this.  I am on holidays at the
moment, so I won't be able to check the current versions of things
for the next week.  I believe the deal is that you get the gcc 3.3
branch from CVS and then go to ftp://ftp.linuxppc64.org/pub/people/amodra
and get the latest patch you find there.

All in CVS as far as I know.

All in Linus' current BK (or the linuxppc-2.5 tree) for 2.5.

For 2.4 I'm not sure; there would be a 5- or 10-line change needed to
arch/ppc/kernel/process.c (to implement CLONE_SETTLS etc.) as well as
any generic backport of futex stuff etc.
