cmake: Don't bundle android.toolchain.cmake.
No need really. And saves me the trouble of manually merging it every
now and then.
On B2G, use curl to download it. Untested, but curl should always exist per

NEON option will be set true -# if VFP is set to NEON. -# -# LIBRARY_OUTPUT_PATH_ROOT should be set in cache to determine where Android -# libraries will be installed. -# Default is ${CMAKE_SOURCE_DIR}, and the android libs will always be -# under the ${LIBRARY_OUTPUT_PATH_ROOT}/libs/${ANDROID_NDK_ABI_NAME} -# (depending on the target ABI).
