Test that files are correctly located in the variant directory even when
Scons does not have a global view of all targets.
Sometimes, it might be interesting to not tell scons about every
targets. For example, one might not read in all the SConscipts of a
hierarchical build for a particular invocation of scons. This would be
done to speed-up a partial rebuild when the developer knows that only
a subset of the targets need to be rebuilt.
