fork: generate stub on no-MMU systems
fork() can be implemented using either the fork or clone syscalls on MMU
systems. Therefore the stub is only generated if neither __NR_fork nor
__NR_clone are defined. The stub code manually undefines __NR_fork on
no-MMU systems in an attempt to enable the stub, but this doesn't work
because __NR_clone is still defined. It is not appropriate to undefine
__NR_clone because clone is available on no-MMU, it is just not capable
of implementing fork.
This patch directly enables the fork stub if __ARCH_USE_MMU__ is not
defined. This eliminates the need to undefine __NR_fork, so this code is
removed
