[PATCH 1/2] New tests, for bugs in Yacc/Lex AM_FLAGS and FLAGS precedence.

[Stefano Lattarini]

* tests/lflags.test: New test, check that user $(LFLAGS) takes
precedence over automake (AM_LFLAGS) and (foo_LFLAGS).  Still
xfailing.
* tests/lflags2.test: Likewise.
* tests/yflags.test: New test, check that user $(YFLAGS) takes
precedence over automake (AM_YFLAGS) and (foo_YFLAGS).  Still
xfailing.
* tests/yflags2.test: Likewise.
* tests/Makefile.am (TESTS, XFAIL_TESTS): Extended accordingly.
