Bootstrapping cabal-install-3.0.0.0 fails with GHC 8.4.4

[bgamari]

Describe the bug The bootstrap script appears to produce an cabal-install install plan using both the bootstrap compiler's Cabal and Cabal-3.0.0.0.

To Reproduce Steps to reproduce the behavior:

Download cabal-install-3.0.0.0 source distribution, extract it, and run bootstrap.sh with ghc-8.4.4:

$ ./bootstrap.sh 
Using gcc for C compiler. If this is not what you want, set CC.
Using /usr/lib/gcc/arm-linux-gnueabihf/6/collect2 instead.

Expected behavior bootstrap.sh should build a functional cabal-install.

System informataion

• Debian 9
• GHC 8.4.4

@bgamari if you manually tweak cabal-install.cabal to be of build-type:Simple, does it still occur?

PS: I tried to reproduce but failed to do so (i.e. it worked for me); I did the following:

docker run --rm -it haskell:8.4.4 bash -i

and then inside this Debian-based container, I needed to apt install ghc-8.4.4-prof (as by default it doesn't have the profiling libs installed), and then unpacked the cabal-install-3.0.0.0 tarball, and ran the ./bootstrap.sh included therein. In the end, a newly build cabal executable was copied into /root/.cabal/bin/.

@bgamari can we close this?

@gbaz I support closing (seems obsolete).
