Subject: [PATCH] make src/ subdir optional

there is at least one examples-only repo (qtwebkit-examples).

we look for tools/ only when src/ is also present, based on the
assumption that if there was only tools/, it would be actually named
src/ (like in qttools). the split between the two is nowadays arbitrary
anyway.
