"Rebuild the gcc toolchain prebuilt binaries for the Android NDK.
Where <src-dir> is the location of toolchain sources, <ndk-dir> is
the top-level NDK installation path and <toolchain> is the name of
the toolchain to use (e.g. arm-linux-androideabi-4.4.3)."

# sysroot at specified API level,and Android build explicit lists header/lib
