SIMD optimizations not always included when compiling via Android.mk

[GoogleCodeExporter]

Attached patch resolves the following issues
- 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.

Thanks this looks ok.
There may be some further work that could be done:
- the libs could be split as in the android tree
- I'm not sure compiling in thumb mode for arm is the best choice, but I 
haven't done any profiling to verify.
