Make arm-linux-androideabi toolchain the default for Android build.

androideabi target is already in upstream GCC. The arm-linux-
androideabi toolchain can be built directly from upstream GCC.
Switching from old special tailored arm-eabi toolchain to the new
arm-linux-androideabi toolchain make us closer to the opensource
community and friendly to all toolchain developers.

kernel still uses arm-eabi toolchain. So we add arm-eabi toolchain
path to PATH.

The arm-linux-androideabi-4.4.x toolchain is built with the same
source as the latest arm-eabi-4.4.3 toolchain except for the
target change patches.
