Trying to resurrect nofib/fibon

Hi all,

I went into the rabbit hole that starts here
https://ghc.haskell.org/trac/ghc/ticket/11501

So far I know that:

   1. fibon is not built regularly by any CI and it bitrotted significantly.
   2. Makefile's for fibon use undefined variables like INPLACE_HSC2HS_PGM.
   Probably those were sourced from ghc/mk/*.mk, but not now.
   3. Haskell courses are pre-AMP (this is easiest to fix).
   4. Makefile's build object files one by one and that fails in case
   modules depend on each other. ghc-paths.mk sorts objects and that gives
   wrong compile order.

Does anybody know a commit-hash or date when it did compile last time?

Knowing that this module (fibno) wasn't used for so long does it make sense
to fix it? How about removing it?
