Loading different constants can be tricky with all the requires in
Homebrew so we want to strengthen the existing checks to make
sure that things are not getting required when there is a performance
penalty. This expands the existing check to include more constants
beyond `Formula` that we don't expect to be defined and that pull
in a lot of other dependencies.
- Refuse to create bottles which have non-relocatable references to
`HOMEBREW_LIBRARY`. This allows us to make all bottles ignore where
`HOMEBREW_REPOSITORY` is (even those that aren't `cellar :any`).
I cannot see any circumstances in which any bottle should link to
anything within `HOMEBREW_REPOSITORY`.
- Remove audit that becomes unnecessary given the above change.
- Relocate references to `@HOMEBREW_LIBRARY@` but don't actually write
any references yet. This will allow us to move to using
`@HOMEBREW_LIBRARY` and remove all relocation of `HOMEBREW_REPOSITORY`
in a future release (2.7.1, most likely).
