Don't pass -m64 to libcc1 on aarch64-linux.

Nowadays, if we use "compile" on aarch64-linux, we'll get the following
error,

(gdb) compile code -- ;
aarch64-none-linux-gnu-gcc: error: unrecognized command line option '-m64'

because the default gcc_target_options returns "-m64" and
"-mcmodel=large", neither is useful to aarch64-linux.
