+Subject: [PATCH] build: de-duplicate _DIRS before calling mkdir
+
+If the build path is long, the contents of the _DIRS variable can be very long,
+since it repeats the same directories very often.
+In some cases, this has triggered an "Argument list too long" build error.

-Subject: [PATCH] build: make _make_dirs robust against too long argument error
-
-_make_dirs currently can fail as _DIRS can be really long and thus go over
-the MAX_ARG_STRLEN limit so it will fail with:
-/bin/sh: Argument list too long
-
-Lets avoid this by stripping the $(BUILDDIR) prefix and then restoring it.
