[powerpc64] compilation --without-tls problems

[Rafael Ávila de Espíndola]

linuxthreads/sysdeps/powerpc/tcb-offsets.sym need a tcbhead_t definition if  
USE_TLS is not defined. But linuxthreads/sysdeps/powerpc/tls.h only defines  
tcbhead_t if HAVE_TLS_SUPPORT is defined or if  __powerpc64__ is not defined.

This causes the build to fail:
