Log Message:
make(1): remove dead code from Var_Subst

The first parameter from Var_Subst had been a literal NULL in all cases.
These have been fixed using this command:

sed -i 's|Var_Subst(NULL, |Var_Subst(|' *.c

The one remaining case was not found because the "NULL," was followed by
a line break instead of a space.

The removed code probably wouldn't have worked as expected anyway.
Expanding a single variable to a literal string would have led to
unexpected behavior for cases like ${VAR:M${pattern}}, in case pattern
would contain an unescaped ':' itself.
