  -x <language>            Specify the language of the following input files   
                           Permissible languages include: c c++ assembler none
                           'none' means revert to the default behavior of
                           guessing the language based on the file's extension


Options starting with -g, -f, -m, -O, -W, or --param are automatically
 passed on to the various sub-processes invoked by arm-linux-androideabi-gcc.  In order to pass
 other options on to these processes the -W<letter> options must be used.
