[openssl-dev] [openssl.org #3737] [PATCH] fix parallel generation of obj headers

[Mike Frysinger via RT]

The current code has dummy sleep/touch commands to try and work
around the parallel issue, but that is obviously racy.  Instead
lets force one of the files to depend on the other so we know
they'll never run in parallel.
