Force one config to build 'out-of-tree' (object files and executables
are created in a tree outside the project source code).

I noticed various out-of-tree issue in the last 2 merge windows.

Pseudo-randomly picked a build from the matrix which covers system + user.

That's odd, because all my pre-merge build tests are out-of-tree
(in-tree is the case I don't cover). Presumably they were only
for specific oddball configs ?

(Not that there's any harm in covering this in travis too.)

Is a three-level nesting really necessary? I think a simple './build' dir should
do.
