Is this fixing a particular autobuild failure ?

Is this fixing a specific bug ?

I do remember someone reporting CMake related issues when building host
packages. Perhaps it was an e-mail. In such a case, there should be a
reference to this e-mail, or bug, or autobuild failure.

Currently, it's not clear whether your patch is fixing an actual
problem (and should be applied to master) or is just nice to have
(should be applied to next).

Of course, I do know that this patch is important and should be applied
to master, but it would be good to have a clearer commit log from that
respect.

Thanks!

Thomas
