android: Update to SDK r16 and ndk r8d. 

SDK r17 is out, however there it only ships a x86 system image for r16 so
it's preferable.

/* ChangeLog for this library:
*
* NDK r5: Handle buggy kernels which report a CPU Architecture number of 7
* for an ARMv6 CPU (see below).
*
* Handle kernels that only report 'neon', and not 'vfpv3'
* (VFPv3 is mandated by the ARM architecture is Neon is implemented)
*
* Handle kernels that only report 'vfpv3d16', and not 'vfpv3'
*
* Fix x86 compilation. Report ANDROID_CPU_FAMILY_X86 in
* android_getCpuFamily().
