That's why its libexec after installing, but I admit to committing the
crime of adding $SRC/build/tests to PATH at times, for convenience when
working on tests.

I think that we are pretty far from being able to handle
igt at tata/toto at subtoto in the CI (quotation needed, Petri?)
and i915/i915_ would be overall less messy of the two.

Oh. Let me check what we can do about it. I'll make it consisten one way or
the other :-)
