Comment (by gelisam):

 I believe this has been fixed in ghc 7.10.1, can we close this?

 At least, the release notes for ghc 7.10.1 claim that the linker API is
 now thread-safe:
 https://downloads.haskell.org/~ghc/7.10.1/docs/html/users_guide/release-7-10-1.html#idp5860656

 See https://github.com/mvdan/hint/issues/68#issuecomment-419088813 for the
 rest of my archeological search on the history of this ticket and why I
 believe this is now fixed.
