7ae225218d Android.mk: SSE2 & NEON updates 
patch by pepijn vaneeckhoudt
- Android.mk should include dec/enc/upsampling sse2 variants. This
  provides sse2 optimizations when compiling for Android/x86
- LOCAL_ARM_NEON should be set to true when compiling for armeabi-v7a.
  Otherwise __ARM_NEON__ is not defined and all neon code is removed by
  the preprocessor.
