Log Message:
make: clean up the check for command line variables

It looked suspicious that to check whether a variable was set via the
command line, the variable value would be needed.  Moving the debug
diagnostic to the calling function resolved this smell.

A variable from the command line scope is never short-lived, so there's
no need to clean up after accessing the variable.

No functional change.
