Old ghc version requires the global package db to be listed first

[qwbarch]

Describe the bug

I'm trying to create a ghcjs project on ghc865. When running nix develop I receive the following error when building the time package:

> Configuring library for time-1.8.0.2..
> Setup: With current ghc versions the global package db is always used and must
> be listed first. This ghc limitation may be lifted in future, see
> http://hackage.haskell.org/trac/ghc/ticket/5977

This is gone when I switched to ghc8107 (as hinted by the error), but I'd like to stick to ghc865 due to a regression.

• Build system: x86_64-linux
• GHC version: 8.6.5
• Haskell.nix version (or commit) used: 1059fc718d83803081cf96f0f9e0d758d5e1ed88

Steps To Reproduce

• git clone https://github.com/qwbarch/ghcjs-fail
• nix develop

Running nix develop will eventually lead to the above error.

Expected behavior

nix develop should succeed, and allow me to proceed as normal.

Is it possible that using --package-db=global could fix this? Not sure if it's even possible to pass this argument over to cabal though.

Closing since ghc865 isn't even supported anymore
