[uClibc] fork() without MMU?

[Alexandre Oliva]

I see that libc/sysdeps/linux/common/syscalls.c has an implementation
of fork() for the !__UCLIBC_HAS_MMU__ case that simply sets errno to
ENOSYS and returns -1.  Is there any point to such an implementation?
AFAICT, this only causes configure tests to get incorrect results, and
think they *could* use fork when it's not really available.

If we really want such a function, how about getting GNU ld to issue a
warning whenever the function is called?
