That's because __private_ss offset from thread pointer is hardcoded in 
gcc, and needs to be constant regardless of glibc configuration (it 
works out to 0x20 for 31-bit, 0x38 for 64-bit) - the same thing is done 
in i386 and x86_64 tcbhead.

I don't have push access, how do I get the patch applied?
