Subject: [edk2][PATCH] BaseTools:Evaluation of undefined macros in dsc files

BZ:https://bugzilla.tianocore.org/show_bug.cgi?id=989

doc:If macro that is not defined is used in locations that are not expressions (where the tools would just do macro expansion as in C flags in a [BuildOptions] section), nothing will be emitted.

This is in fact not what happens.Instead, the text
$(MACRO1) is emitted verbatim into the Makefile and left the for make to process.
