what version of gcc are you using ?  does it support TLS for your target ?

i doubt it ... i configure the first pass gcc in Gentoo with --disable-threads 
all the time and ive never hit this error when building nptl glibc unless the 
gcc version didnt support TLS for the target (for example, testing for 
__thread with mips and gcc-3.4.4 will fail since mips doesnt have TLS until 
like gcc-4.1+)

the only gcc configure option that'd affect this i think is the target name
