   4 Subject: [PATCH] build: make _make_dirs robust against too long argument error
   5
   6 _make_dirs currently can fail as _DIRS can be really long and thus go over
   7 the MAX_ARG_STRLEN limit so it will fail with:
   8 /bin/sh: Argument list too long
   9
  10 Lets avoid this by stripping the $(BUILDDIR) prefix and then restoring it.
