[TEGRA2] Initial Tegra2 support:
Disable neon optims for xbmc and libs (ffmpeg) (configure.in)
Disable neon optims for depends (tools/android/depends/Makefile.include.in)
Ignore neon-check on XBMC startup (tools/android/packaging/xbmc/src/org/xbmc/xbmc/Splash.java)
Fix non-neon compilation with GCC 4.4.3 toolchain (xbmc/cores/AudioEngine/Utils/AEConvert.cpp)
