haskell.compiler.ghc8102Binary: Add check for arch-specific libraries.
With this check, we no longer don't notice when the upstream bindist changes its dependencies (e.g. because a newer Debian version is used that uses a new `ncurses` version).

# * You can find the `fileToCheckFor` of libraries by running `readelf -d`

# on the compiler binary (`exePathForLibraryCheck`).

# * To skip library checking for an architecture,
|

# set `exePathForLibraryCheck = null`.
|

# * To skip file checking for a specific arch specfic library,
|

# set `fileToCheckFor = null`.
