The patch gives more detailed description of cortex-A9's

From now on, the general Android toolchain will be arm-linux-androideabi.
arm-eabi toolchain built from this source does not contain Android specific
configurations and will only be used to build Android kernel.
Read recent changes in toolchain/build/README for more details.
