Verify that applying env.Tool('qt3') after running Configure checks
works properly. This was broken in 0.96.95.
The configuration here is a moderately stripped-down version of the
real-world configuration for lprof (lprof.sourceforge.net). It's probably
not completely minimal, but we're leaving it as-is since it represents a
good real-world sanity check on the interaction of some key subsystems.
