GHC panics when linking with an archive and using an annotation

GHC panics when compiling code with an annotation and linking with an archive (a .a file). I think this is the same as #9438, but I have a really simple test case consisting of the following two files:

// add.c
int add2(int x, int y) { return x + y; }

-- app.hs
{-# ANN module () #-}

main :: IO ()
main = return ()

First I make an archive:

$ gcc -c add.c -o add.o
$ ar libadd.a add.o

And then the following fails:

$ ghc -ladd -L. app.hs
[1 of 1] Compiling Main             ( app.hs, app.o )
ghc: panic! (the 'impossible' happened)
  (GHC version 8.2.2 for x86_64-apple-darwin):
	Loading archives not supported

Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug

make: *** [app] Error 1

The attached tar.gz has these source files and a Makefile to run the above. I've tested it on OS X 10.11 and Linux, both with GHC 8.2.2, and the behavior is the same.
