Add syscall stubs for __vfork14(). These are basically copies of Ovfork.S
...
with the syscall numbers changed.
Since 4.4BSD vfork(2) did not share address space, Ovfork.S could be changed
to be identical to fork.S (modulo syscall numbers). __vfork14.S, however,
needs to remain separate since with a shared address space, the stub needs to
pre-decrement the stack and do an indirect jump to the return address, so that
the shared stackframe is still there when the parent returns. (Obviously,
this does not apply to systems which to not build stackframes on leaf calls.)

A foolish consistency... gen, net, and string all get MD sources
...
specified by including a Makefile.inc from the appropriate MD directory.
stdlib doesn't do that, but there's no reason that it shouldn't (and
it'd be nice to eliminate the 'if's from the MI stdlib Makefile.inc).
