 This is a follow-up to #11202. The fix there is platform specific, but the
 problem is compiler/assembler specific.

 Sample of errors:
 {{{
 /tmp/ghc4044980_0/ghc_2.s:681:2: error:
      error: unknown directive
             .hword 4
             ^
     |
 681 |         .hword 4
     |  ^

 }}}

 Repro command:
 {{{
 $ cat A.hs
 module A where
 main = putStrLn "Hello"
 $ ./inplace/bin/ghc-stage2 -g -pgma=clang++ A.hs
 }}}

 One workaround that I've found:

 {{{
 $ ./inplace/bin/ghc-stage2 -g -pgma=clang++ -opta=-no-integrated-as A.hs
 # succeeds
 }}}
