Suggest:

	* sysdeps/unix/Makefile ($(objpfx)stub-syscalls.c): Use $$ver.

OK with that.

Thankfully this broke only just recently at 2013-09-11 by
0a834ddecbb08b79cbcf7d9460ab3d3d539c9962. So there has been no
release with this fix for removing bash-isms.

My gut says that on all other targets we probably don't have
any stubs so this never showed up because this code was never
called. Every other architecture probably has fanotify_mark
generated by a syscall wrapper, not a syscall stub.

So the followup question is why does sh use a do-nothing
stub for this?

Cheers,
Carlos.
