Add PhysicsEffects to Extras. The build is only tested on Windows and Android.
The Android/NEON optimized version of Physics Effects is thanks to Graham Rhodes and Anthony Hamilton, See Issue 587

# BULLET_PFX_ROOT_CYGWIN = /cygdrive/d/tools/PhysicsEffectsRootPath

# The reason for *not* just setting local path := $(call my-dir)

# is that we wish to access local source files that are *not*

# located in a "jni" subfolder and *not* located in a subfolder

|

# Android NDK projects that fit neatly into the Bullet/PhysicsEffects

# forcing the "jni" and subfolder structure that Android SDK/NDK

# prefer for pure Android projects.
