Comment (by ryandesign):

 I don't think #53150 is relevant. #53150 is about `-export_dynamic` being
 automatically added when `-rdynamic` is used. In the case of glib2 here,
 `-rdynamic` is not being used. The error is only happening when building
 the gmodule tests, so I think it is because the file
 gmodule/tests/meson.build is explicitly asking for `-export_dynamic` by
 using `'export_dynamic' : true`:
