[Yonghong Zhu <yonghong.zhu@intel.com>]

Current it only support the system environment variables in the !include
statement, $(WORKSPACE), $(PACKAGES_PATH), $(EFI_SOURCE), $(EDK_SOURCE),
$(ECP_SOURCE), this patch extend the usage to support the Global macros
and the macro which defined before the statement.
