Make it an error if there's more than one build rule for a single output.

Make it an error if there's more than one build rule for a single output.

This warning seems to not fire anywhere at the moment. Make it an error to make
sure it stays that way.

If this breaks your bot, please a) revert b) let me know.

The build error will look like "multiple rules generate X [-w dupbuild=err]".
