Well, in the case of just passing "-s", we already have the
ccache-stats target.

But I agree that for all other options, adding another
ccache-<something> target would be impractical, so probably your
proposal of CCACHE_OPTIONS makes sense.

Can you respin your patch on top of the latest master, and add an
update to the manual (we already have a section about ccache support,
see http://buildroot.org/downloads/manual/manual.html#ccache).

Thanks!

Thomas
