Given the current state of OS X compilers, the original fails_with behavior is becoming less useful, mostly resulting in build failures each time the compiler is updated. So make the following changes: When a build is specified, we retain the old behavior: switch compilers if the available compiler is <= the build, don't switch if it is > the build. When no build is specified, unconditionally switch compilers, and don't output the advice message. This allows us to mark formulae as perpetually failing, avoiding the need to update formulae each time a new compiler build is made available. As a bonus, this makes the logic much easier to reason about. Closes Homebrew/homebrew#18175.

Building with Clang configures GHC to use Clang as its preprocessor,

which causes subsequent GHC-based builds to fail.
