cabal-install suppresses errors when asked to build extra-packages

Apparently, if cabal is asked to build a package listed in `extra-packages` and the package fails with compiler errors, no error is printed to stderr.

To reproduce, create this minimal `cabal.project` file in an empty folder.
```
allow-newer:
*:*

extra-packages: bytestring-show-0.3.5.6
```

Now build with a sufficiently recent compiler
```
$ nix-shell -p haskell.compiler.ghc925 --run "cabal v2-build bytestring-show"
Warning: There are no packages or optional-packages in the project

```

```
$ cabal --version
cabal-install version 3.8.1.0

```

I would expect the compiler errors to be printed to stderr.
