It should also be noted that by using those opts, it's still only going
to be 32 bit. To force compiling 64 bit requires -m64 -- but that wont
do you any good with a 32 bit kernel... At the moment, it's not worth
the effort to try and compile 64 bit apps until we get a 64 bit ISO
going for it, and even then, it will take some effort to create and to
maintain.
