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.)

ieee.h and ldexp.c taken from the powerpc port, for the benefit of

68040 and 68060 owners.
With ``make M68040=1'' or ``make M68060=1'', we build a libc where the ldexp()
doesn't use excessive amounts of system cpu time.
Without any of those defines, the normal assembler version using FSCALE is
included, for the benefit of M68020 and M68030 users, or M68040/M68060 users
where the ldexp performance is no bottleneck.
[Its not yet worked out how to include both library versions in a binary
distribution, but you can build your own from source now if you need it.]
For details, look at PR 3105.
