+Subject: [PATCH] Don't add multiarch paths
+
+The add_multiarch_paths() function leads, in certain build
+environments, to the addition of host header paths to the CFLAGS,
+which is not appropriate for cross-compilation. This patch fixes that
+by simply removing the call to add_multiarch_paths() when we're
+cross-compiling.
+
+Investigation done by David <buildroot-2014@inbox.com>.
