* m4/python.m4 (AM_PATH_PYTHON): Fix the invocation of

AC_PATH_PROGS to correctly define PYTHON as `:' when no interpreter
is found (this worked correctly only when a minimal version was
passed to AM_PATH_PYTHON).  Report from Stepan Kasal.
(_AM_PYTHON_INTERPRETER_LIST): Define using m4_define_default,
so we can easily override the list from the test suite.
* tests/python11.test: New file.
* tests/Makefile.am (TESTS): Add python11.test.
