Accepting request 769886 from devel:languages:haskell:ghc-8.8.x

- use ghc-bootstrap-helpers on all archs
- lower build env requirements on riscv64 
  * make sure we can build on smaller systems
  * adjust parallelism so we don't hog big workers for almost a week
  * many thanks to Stefan Bruens for pointing out the issue and
    helping with the solution
