### Please describe the problem.
Working to update the macOS Homebrew Formula for git-annex 7.20191009 and I'm receiving a build error using the Homebrew build system to build via ghc 8.6.5 on macOS 10.14.6:

Is this an artifact of ghc 8.6.5 vs 8.8.1?
### What steps will reproduce the problem?
Updated the Homebrew Formula with the appropriate changes.
[[!format sh """
# brew install ghc@8.6
# brew install --verbose --build-bottle git-annex`
"""]]
### What version of git-annex are you using? On what operating system?
git-annex 7.20191009
macOS 10.14.6
The Glorious Glasgow Haskell Compilation System, version 8.6.5
### Please provide any additional information below.
[[!format sh """
# If you can, paste a complete transcript of the problem occurring here.
# If the problem is with the git-annex assistant, paste in .git/annex/daemon.log
# End of transcript or log.

### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
git-annex has been awesome for managing a massive collection of raw images and video clips across several storage targets and editing systems.
