Address NewApi lint warning in X509Util.java.

Android lint helpfully warns that we're using an API added after ICS.
We're doing this deliberately and safely (only on JB MR1 and up), so
suppress the lint warning.

Fix compilation of base for arm64

Add support for the architecture to build/build_config.h (define
new macro ARCH_CPU_ARM64 to identify the CPU architecture and
set the other appropriate macros to 1).

Fix DEBUG_BREAK_ASM() macro to expand to the correct instruction
on arm64 cpu (as instruction set is not compatible with previous
version of ARM instruction sets).
