Patch Set 4:

Indeed. As noted in the patch itself, I believe we would need an upstream solution in the long term if we decided to adopt use of ccache.

This patch set is not intended as a permanent solution.
It is a proof of concept which allows us to evaluate advantages ccache  puts on our table, before investing time with getting upstream involved.

I think we should at least investigate how ccache affects our jenkins builds jobs before talking to upstream. That should show whether additional effort would be well spent.

I invested a signifcant amount time (4 hours) to figure out why ccache wasn't working out of the box. This patch set saves other people the trouble of trying to get it to work.
