Issue Description:
It appears as if the reference to stdout is causing a compilation failure:

assert(statbuf.st_mode == S_IFREG | S_IRUSR | S_IWUSR | S_IXUSR)stdout should be defined on Android, though. My guess is that it should be defined in stdlib/public/Platform/Platform.swift or it should be imported from Android's libc, Bionic.
Prerequisites:
-
An Ubuntu 15.10 development environment capable of building Swift from source.
-
A physical Android device.
Helpful skills:
Familiarity with Swift, ClangImporter, and the Android libc would all be helpful, but certainly not required. The most helpful skill here is probably patience as you compile and run the tests again and again. 🙂
Starting point:
Follow the instructions in docs/Android.md to build and run the test suite on a physical Android device. Confirm this test still fails.
