[TIMOB-10879] Tooling: Android SDK build (scons etc) fails on Windows when using NDK 8b

Fail case / test case

You need a Windows machine which is configured to build the SDK. * Install latest NDK (r8b) http://developer.android.com/tools/sdk/ndk/index.html * Be sure to set your ANDROID_NDK environment variable to point to it (_before_ opening the command window in which you'll run scons). * Open a command window. * Test to be sure that the right NDK will be used: run echo %ANDROID_NDK% and make sure the result is the path to r8b. * Go to the titanium mobile source folder and try to build the sdk with scons. * Soon after the build starts it should stop with an error like this:

     [exec] process_begin: CreateProcess(NULL, rm -f src/native/../../generated/
*, ...) failed.
     [exec] make (e=2): The system cannot find the filerm -f src/native/../../ge
nerated/*
     [exec]  specified.
     [exec] make: *** [ti-clean] Error 2

BUILD FAILED
