If it works, it looks ok to me. 

Actually this may even be needed for other architectures. It is still 
(ie in 2.3.6) use for alpha, sparc (64-bit flavour) and i386. I have 
tried to build the i386 package with --with-__thread now that we have 
TLS support on i386, but it failed. No time to investigate though.

Also we still have a few architectures without TLS support (arm, hppa,
m68k, mips, mipsel), at least in 2.3.6.

Things may have evolved with 2.4 though, I haven't checked.

Bye,
Aurelien
