+Subject: [PATCH] perf build: Do not fail on missing Build file
+
+Allow nesting into directories without Build file. Currently we force
+include of the Build file, which fails the build when the Build file is
+missing.
+
+We already support empty *-in.o' objects if there's nothing in the
+directory to be compiled, so we can just use it for missing Build file
+cases.
+
+Also adding this case under tests.
