You need to download the 10.11 Command Line Tools from download.apple.com
and reinstall them over the Xcode 8 command line tools, which are for 10.12
and will have problems like this. (Apple intends to correct this in Xcode
8.1.) You need a free Mac Developer account for this, or maybe you can find
the 10.11 tools elsewhere. You will then need to clean and rebuild ghc.
