 Rework how iOS does linking (#8127)

 iOS has some particular constraints about how applications can be built:

  * We must generate a static library (.a) since XCode does the final
    link.
  * We need to carefully give the right set of arguments to libtool in
    the case we're generating an archive.
  * Dynamic linking isn't supported.
  * It can only be done on OS X.

 This patch cleans up all of the above. We add a new flag `-staticlib`
 (only supported on Darwin) that allows us to produce archive files using
 libtool, and a -pgmlibtool flag to control which 'libtool' executable to
 use.

 This fixes #8127. I believe this is the last piece missing from the iOS
 cross compiler.
