Log Message:
make(1): don't require nested variables to be defined in conditions

This code only applies to lint mode (-dL) for now.  After a test phase
and a thorough check for possible side effects, it will be activated in
normal mode, too.  Having this code in lint mode is required to run
src/build.sh, which relies a lot on using variables with undefined
nested variables in conditions.

In the default mode, any errors about nested undefined variables are not
printed since in Var_Subst, oldVars is true.  Therefore, it is not urgent
to properly handle these nested variables correctly there.
