Skip other.test_odin_validation if SpiderMonkey is not present, since it is a SpiderMonkey-specific test.
mark emscripten_GetProcAddress as needing strstr, which is now in libcextra
When we build native OSX executables with Clang, we must tell Clang which OSX SDK version we are targeting. Add a function CLANG_NATIVE_ARGS() that returns a list of compiler args that need to be appended when building native executables for the current platform, which for OSX automatically find an SDK to target. Make the machinery lazy and cached so that it's not invoked if native executables are not built, and that it's invoked only once when needed. Fixed test other.test_bad_triple on OSX.

1.15.0
Added preliminary support for the SDL2 touch api. Missing items:
  1. Timestamps
  2. TouchID (the Device ID)
      As inline with the SDL spec, we will pass a touch ID of
      `SDL_TOUCH_MOUSEID` for touch events that are simulated by the
      mouse so games can rely solely on touch events if they like.

Includes the SDL2 Copyright notice on the headers that contain SDL2
content.
Includes a fix to SDL_PeepEvents.
Apply kripken's code formatting review to michaeljbishop's SDL2 touch pull request.
Implement SDL2 touch event timestamps and add a digital 0/1 pressure if no pressure data is present.
