allow passing parameters to gtkdoc-check and only grep them from Makefile as a fallback
Eventually, it would be nice if gtkdoc-check
accepted command line parameters more naturally, and only fell back to environment variables and reading Makefile.am
if the command line parameters weren’t passed — but I don’t have time to work on that (sorry).
In my mind, something like the following would be good:
gtkdoc-check $builddir/path/to/docs $doc_module $doc_main_xml_file
