This broke configure in subtle ways resulting in #25076 where hadrian
didn't end up the boot compiler it was configured to use.

This reverts commit 209d09f52363b261b900cf042934ae1e81e2caa7.

Changes the error message when trying to lookup names on GRE that

behavior now points the user to the missing name, instead of the
name clash which would be unhelpful in solving their compiling issue.
