Obviously, the sid archive stands much a better chance with the sid 
compiler, so there's no rush to build 4.5 if sid is the objective (?)

BTW, you'll need kernel headers with TLS support before you can build libc 
with TLS/NPTL, and you need that before you can build gcc with TLS.

This amounts to a circular dependency. When bootstrapping a cross 
toolchain, the cycle is broken by building some libc object files early 
and by building several compilers. Given a complete cross toolchain, there 
are other solutions available.

The gcc test suite would inspire more confidence, if you haven't run it
