[PATCH] Mention implementation file names in benchmarks for fast/slow path functions

[Siddhesh Poyarekar <siddhesh at redhat dot com>]

Hi Andreas,

Here's a patch you had asked for to add the comments mentioning file
names where the various fast/slow paths are implemented.  Does this
look OK?

Siddhesh

	* benchtests/Makefile: Mention files in which fast and slow
	paths of math functions are implemented.
