Issue Description:

During the port of Foundation to Android apple/swift-corelibs-foundation#622 it was found that it was not possible to gate the code of NSTask.swift using @available(Android, unavailable) or where this could be readilly updated in the compiler source. It’s strange as the construct #if os(Android) will give a warning if mistyped so the Compiler has some awareness of Android.

@available normally controls versioned OSs, and works with #available to do dynamic checks, but it is reasonable for this to work. We still haven't worked out all the queries around os(…) though: how do we check for different Linux distros, or all Apple platforms, or Cygwin+MinGW+MSVC? I'm not sure which of those need to go into @available.

Thanks Jordan, Sounds like it might take a while to spec out and arrive downstream.
