maintcheck: avoid yet more spurious failures (1) The 'sc_tests_makefile_variable_order' maintainer check is too strict sometimes, blaming automake for outputting out-of-order variables when this is in fact due to the result of post-processing of third-party tools or custom test code. * t/tap-doc2.sh: Ensure the final Makefile.in (that we hack by hand) is removed, to avoid a spurious maintainer-check failure. * t/gettext-macros.sh: Ensure that any leftover Makefile.in (that is generated by gettext/autopoint) is removed, to avoid a spurious maintainer-check failure.
