I'm working on sh4 to provide an NPTL support. I just force the
NPTL support of sh4 in the configuration and add the cpu_set_tls
using the env->gbr. I have sh: 
../nptl/sysdeps/unix/sysv/linux/sh/../fork.c:138: __libc_fork: Assertion 
`(self->tid) != ppid this assertion in tforhe libc code. The 
child_tidptr is nil, so I can't set the tid for the child. I don't want 
to fix this issue but just understand what happen.

Regards Michael
