@Andreas - this slightly conflicts with your WIP patchset. Do you think it makes
sense to get this one merged first?

It would also need a review, I'm not going to push this without, even though I 
believe it's the most suitable and straightforward way to get all the issues 
fixed that it covers (up-to-date check wrt. double-make, log-spam, log prefixes,
common.mak sanity and MSVC-CLang build). 

Thanks,
sw
