Switch NDK from r10e to r12b

This CL completely removes --android_compiler option since we now only
support Clang toolchain for Android target binaries.  GCC toolchain
bundled in Android NDK is going to be deprecated shortly [1].

This Cl also adds following build targets on Travis-CI.
 - Android (arm64)
 - Android (x86)
 - Android (x86_64)
 - Android (mips)
 - Android (mips64)

Closes #273.
