+# GAR uses PARALLELMFLAGS to propagate make options (judging by the name, mainly
+# intended for -j). Options are determined via MFLAGS which also contains other
+# options, thus we need to filter harmful ones. e.g. -I breaks upstream builds
+# that use non-gnu make (Fatal error: Unknown option `-I'). Info on M*FLAGS:
