[Stefan Gränitz via Phabricator via llvm-commits]

Was this tested? I am not getting `APPLE` here:

  $ uname -s
  Darwin

https://cmake.org/cmake/help/v3.4/variable/CMAKE_HOST_SYSTEM_NAME.html says:

> On systems that have the uname command, this variable is set to the output of uname -s. Linux, Windows, and Darwin for Mac OS X are the values found on the big three operating systems.

What motivated the decision against `CMAKE_HOST_APPLE`?
