Unable to build git-annex

[Duncan Bayne]

Hi,

Firstly thanks for maintaining Haskell on FreeBSD!  This has proved very
helpful to me as I use a couple of Haskell-based tools (shellcheck,
git-annex) on a regular basis.

I'm currently unable to build git-annex on FreeBSD 12.0; I filed a bug on
git-annex, but they have closed it claiming it's likely a bug with my
Haskell toolchain.

https://git-annex.branchable.com/bugs/Can__39__t_compile_on_FreeBSD__58___alex__44___StateVar__44___SafeSemaphore__44___IfElse_fail/?updated

This _used_ to work on 11.2 so part of me suspects (l)user error on my
part as the cause :)

The (abridged) errors are:

IfElse-0.85: configure
SafeSemaphore-0.10.1: configure
StateVar-1.1.1.1: configure
alex-3.2.4: configure

Versions of things are:

+ FreeBSD 12.0-RELEASE r341666 GENERIC amd64
+ Stack 1.7.1 x86_64
+ GHC 8.4.3.
