+Subject: [PATCH] Revert "Revert "meson: use c_args in generator scripts
+ (#10289)""
+
+This reverts commit 0e3cc902faec4f18d5fa606396f602b08bc94e27.
+
+Fixes #10288.
+I have confirmed that this does now fix cross-compilation.
+It appears that changes upstream in Meson, probably mesonbuild/meson#5263, have made the original MR, #10289, work now.
+
+This needs to be tested to ensure that it doesn't break Travis CI like when it was reverted in #10361.
