nptl: Disable fork and atfork on MMU-less systems.
They do not work on MMU-less systems.
For atfork, implement a hidden function that always returns EPERM.
* libpthread/nptl/sysdeps/unix/sysv/linux/fork.c: Disable if
__ARCH_USE_MMU__ is not defined.
* libpthread/nptl/sysdeps/unix/sysv/linux/libc_pthread_init.c
(__libc_pthread_init): Handle __ARCH_USE_MMU__.
* libpthread/nptl/sysdeps/unix/sysv/linux/register-atfork.c: Likewise.
* libpthread/nptl/sysdeps/unix/sysv/linux/unregister-atfork.c: Likewise.
