[PATCH] New make target to only build benchmark binaries

[PATCH] New make target to only build benchmark binaries

[Siddhesh Poyarekar]

For situations where we are cross-building or where we want to avoid
building on the target system, we want a way to only build benchmarks
and then copy them over to the target system to run them.  I have also
added a simple enhancement for the 'bench' target where all benchmark
binaries are built and then the benchmarks executed.

Tested on arm.  I'll push this tomorrow if there are no objections.

	Makefile.in (bench-build): New target.
	Rules (PHONY): Add bench-build target.
	benchtests/Makefile (bench): Depend on bench-build.
	(bench-build): New target.
