cachebench: new package

This patch adds the cachebench package.

Cachebench presents itself as a program to empirically determine some
parameters about an architectures memory subsystem. It can be used to
have an idea of the performance of the cache support. It has been
integrated into LLCbench (Low Level Characterization Benchmarks), but
currently only Cachebench is supported by Buildroot. The only
difference with mainline is a patch which add a script to be able to
generate data ready to bu used by gnuplot without having to use 'make'
which is usually not present on embedded target.

Please don't take this patch I found two typos in the script, I am
currently testing the fixes, and I will sent a new version soon.

Nitpick of the day: to *be* used.

Ok. Since this is not really a patch (you are adding a file that don't
rely at all on existing source file from the project), why don't you
just add this file to the package folder, and install it ?

But if you still want to use a patch, please use your Signed-off-by here.

Hmmm, here I would call the package llcbench. But you were saying that
you were building only the cachebench package, so I'm not quite sure
about what to do, except build the whole tool set and not just
cachebench (if it is possible?)

I thought I was using a speller to avoid this kind of typo...

Indeed using a file should be better.

The 3 programs included in LLCBench share a kind of common configuration file, but
each one have to be compiled separately.

built will run as expected
