Hi Andrew,

Yes, it copy from  BaseTools/Conf/tools_def.template to Conf/tools_def.txt, so if we make any changes in Conf/tools_def.txt will be over write by BaseTools/Conf/tools_def.template, then why we have to edit txt file instead template. Please confirm we have to edit template file or txt file. and we are made changes such as setting target and appending LDFLAGS on template file.
