Summary:                    [patch] ARG Variables are not overwritten when using
empty values on macros
Description: 
If you pass emtpy values inside of a macro to another macro, the ARG
arguments are not overwritten:

&MacroOne("one","two","three","four");

macro MacroOne (var1, var2, var3, var4) {
   var3=""; // also tried var=${} here - makes no difference
   &MacroTwo(${var1},${var2},${var4},${var3});
};

macro MacroTwo (var1, var2, var3, var4) {
   Verbose("Arg1 ${ARG1} Arg2 ${ARG2} Arg3 ${ARG3} Arg4 ${ARG4}");
};

As you can see in the output below, four is also assigned to var4 in
MacroTwo although it is passed as an empty value.
