+Subject: [PATCH] Include environment variable GCC_HONOUR_COPTS in hash.
+
+The OpenWRT patch, 910-mbsd_multi.patch, to GCC adds an extra
+compilation flag, -fhonour-copts, which is influenced by an
+environment variable called GCC_HONOUR_COPTS.
+
+Include this environment var in the hash calculation as otherwise
+the gcc stdout warning from a previous compilation might be shown
+where, even when GCC_HONOUR_COPTS is in 's'ilent mode.
+
