My opinion on this is, that there are systems supporting threads
with uClibc, which do not have TLS support. Linuxthreads.old does
not make use of TLS. When you build for coldfire or ARM noMMU, tls 
is not available and it should be disabled while configuring gcc.

I am wondering why Blackfin enables TLS without any NPTL support.
