Ouch, our new VPATH rewrite doesn't work in some corner situations with GNU
make 3.81 (at least) causing failures of tests 'yacc-subobj-nodep.test' and
'lex-subobj-nodep.test' :-(

*But* it turns that our by-hand VPATH rewriting isn't really needed after
all -- GNU make, starting from at least version 3.78, takes care of that
automatically when '$<' is used!  Yippy!

So we can simplify our rules even more, *and* increase portability while
doing so.  Sometimes life is sweet :-)

What about the attached patch?  I will push by tomorrow if there is no
objection.

Thanks,
  Stefano
