Remaining cleanup issues

[Pavel Roskin]

Hello!

I changed tests/mktests.sh so that the AC_REQUIREd macros are also tested
(just for myself, it's not in the patch).  There were 4 failures:
AC_INCLUDES_DEFAULT, AC_F77_LIBRARY_LDFLAGS, AC_PROG_CXX and
AC_PROG_CXXCPP.

Obviously, AC_INCLUDES_DEFAULT should not be used on the top level since
it doesn't expand to shell code.

AC_F77_LIBRARY_LDFLAGS calls _AC_PROG_F77_V_OUTPUT that removes
"conftest.*" after linking, thus leaving "conftest".

Both AC_PROG_CXX and AC_PROG_CXXCPP are indirectly calling
_AC_PROG_CXX_EXIT_DECLARATION, which uses "break" and doesn't clean up
after that.

ChangeLog:
        aclocal.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Remove conftest*
        after using break.
        (_AC_PROG_F77_V_OUTPUT): Remove conftest*, not conftest.* after
        linking.
