+Subject: [PATCH] kbuild: Disable gcc plugins
+
+The GCC plugin feature leads to different kernel configurations on what
+ought to be equivalent build systems because they depend on the build
+hosts native compilers rather than the cross compilers needed for the
+target. This causes problems with module symbol version mismatches.
+
+Disable GCC plugins for all build hosts.
+
+Advanced build script hackery borrowed from a patch by milhouse.
