[openib-general] perftest-03: put C code in .c file

[Grant Grundler]

Hi Michael,
Patch below fixes up the Makefile and getclock.h so C code is in C files
like people expect.

Unfortunately, I don't know how to make svn diff treat a new file as
part of the diff.  "cvs -upN" is how I would do it for cvs.
svn just (correctly) whines it doesn't know about the new file.

But it's easy to generate get_clock.c:
	cp get_clock.h get_clock.c
	edit get_clock.c and delete everything related to get_cycles().
	(This preserves the copyright/license too)

*THEN* apply the patch below.

thanks,
grant
