Don't compile or link in EU::CBuilder's base class testing.

Remove the tests that try to send actual compile and link commands
to the shell and predict what their output will be.   That can't
be done portably in the base class -- that's what the overrides
are for.  Testing that properties get populated correctly and so
forth should be reasonably portable, though there is no guarantee
some of these won't be overridden as well (but leave them in for
now).
