Auto merge of #67172 - jethrogb:jb/bootstrap-linker, r=alexcrichton

Bootstrap: change logic for choosing linker and rpath

This is a follow-up from #66957 and #67023. Apparently there was one more location with a hard-coded list of targets to influence linking.

I've filed #67171 to track this madness.
