[FYI] {yacc-work} yacc tests: fix bug in 'yacc-cxx.test'

[Stefano Lattarini]

* tests/yacc-cxx.test: Enable `errexit' shell flag (the lack of
which was masking the bug).
(bar.cxx): Rename to ...
(bar2.cxx): ... this, otherwise automake will (correctly) complain
that object `bar.o' is created by both `bar.cxx' and `bar.c++'.
(Makefile.am): Adjust.
