[Stefano Lattarini]

* tests/lexlib.test: New test, checks on @LEXLIB@ and $(LEXLIB).
* tests/lex12.test: New test, checks on AC_PROG_LEX and
AM_PROG_LEX.
* tests/lex13.test: New test, checks on AM_PROG_LEX.
* tests/lex3.test (configure.in): Use AC_PROG_LEX, not
AM_PROG_LEX.
* tests/lex5.test: Likewise.
