Build failure with GHC 8.0.2 and cabal-install 3.14

```
$ cabal build -w ghc-8.0.2
Resolving dependencies...
Build profile: -w ghc-8.0.2 -O1
In order, the following will be built (use -v for more details):
- entropy-0.4.1.10 (lib:entropy) (first run)
unrecognized 'configure' option `--with-doctest=/Users/abel/.cabal/bin/doctest'

unrecognized 'configure' option `--with-runghc=/Users/abel/.ghcup/ghc/8.0.2/bin/runghc-8.0.2'
Error: [Cabal-7125]
Failed to build entropy-0.4.1.10. The failure occurred during the configure step.

$ cabal -V
cabal-install version 3.14.1.0
compiled using version 3.14.1.0 of the Cabal library
```
This could be due to a cabal-install/Cabal-library incompatibility. E.g. `cabal-install` passes these options to a `Setup.hs` that is build with an old version of `Cabal`-the-library that does not understand these flags.
