This variable is supposed to be internal. I would like to be able to
change it's meaning or replace it with something better with minimal
changes in the other code. So I prefer it to be used only by few
"low-level" dependency functions.
This is not some strict rule, in other situation I may agree that using
$test_subtest_missing_external_prereqs_ directly is the best option.
But in this case, introducing a local variable with clean and simple
meaning is better IMO.
