Using --enable-local-rust causes stage1 and stage2 binaries to be linked with system rust

[tdaede]

I am attempting to use a system install of rust (from binary form) as the stage0 of a local rust build. I need to do this because stage0 snapshots are not available for my architecture. When I do this using --enable-local-rust, the stage1 and stage2 rustc binaries end up being linked with system shared libraries, e.g. the original stage0 snapshot binaries. This causes them not to work due to missing symbols.

I think I hit the same problem on DragonFly!

Triage: I am not sure if anything has changed here or not. @tdaede have you still seen this recently?

Make's now gone, so closing.
