Hi The current main Makefile incorrectly identified my ld as one that supports --build-id (it didn't). The problem is fixed by upgrading to the latest binutils, version 2.18, which does, but somehow I suspect that this wasn't what was intended. For what it's worth, I was running with slackware's binutils-2.17.50.0.17.
