[git commit] spawn: fix building on no-mmu systems

[Mike Frysinger]

commit: http://git.uclibc.org/uClibc/commit/?id=e2a32f75141fe523df98f4e25186391b345668d0
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/master

We don't have fork() on no-mmu, so if we're going to end up calling it,
return ENOSYS instead.
