Description

From a conversation that began in https://github.com/rust-lang/cargo-bisect-rustc/pull/53#issuecomment-590008841

It would be helpful to be able to define link failure errors as the regression definition. This could be supported through a new hard coded field as of the #53 changes, or supported with a new command line option that takes a substring for the stderr message search.

Research direction

Start with the changes from pull request #53 and the linked issue conversation, then trace how regression definitions and stderr messages are currently handled. Define support for link-failure regressions through the agreed hard-coded field or command-line substring option, and verify that the bisect process recognizes the matching linker failure.
