    Don't strip binaries when doing a debug build.
    
    This patch allows the developer to build the external binaries with
    DEBUG=1 which ensures that the final binaries are not stripped from any
    debug symbols.
    
    This makes the binaries useful together with Google's simpleperf
    profiler for Android.
