The main issue here is that Clang seems not to be choosing link time
optimizations by default, while the make-based run calls it explicitly. So
it is possible to achieve the same effect (ie. cover LTO) by turning them
on on some runs (for all types of tests on all hardware configurations).

I'd strongly recommend that we use only one test style (LNT) everywhere,
and that we should test LTO more effectively.
