I don't set COMPUTE_HEADER_DEPENDENCIES, so it defaults to "auto".
The automatic detection determines that the compiler doesn't support
it, so it's then set to "no".  CHECK_HEADER_DEPENDENCIES isn't set
either, so about 20 lines below the dep_dirs assignment you quoted,
dep_dirs is cleared:

 dep_dirs =
