ghc 8.4.2 on OS X: clang: warning: argument unused during compilation: '-nopie'

% cat Nopie.hs
module Nopie where

main :: IO ()
main = putStrLn "hi"
% ghc -fforce-recomp -c -fhpc Nopie.hs
clang: warning: argument unused during compilation: '-nopie' [-Wunused-command-line-argument]
clang: warning: argument unused during compilation: '-nopie' [-Wunused-command-line-argument]

This happens for every source file when -fhpc is given, but also happens on links even when -fhpc isn't given. With -v, I see a call to gcc with -no-pie. When I run the same compile with ghc 8.4.1, I see the same call to gcc, only without that -no-pie flag, so this is new. It seems to be a harmless warning, but really clutters up the output.

Incidentally, it looks like the particular spelling of -no-pie was added to LLVM a year ago due to ghc: https://reviews.llvm.org/D35462 Not sure if that's relevant.
