In this case different ASEs like mips16, or mdmx, or ... instead of chip
architecture. Basically allow the loader to decide whether or not an app
is ok for the platform based on the ASEs the chip supports. I.e.
something could be compiled for mips32 but supporting mips16 and mdmx,
vs. for a particular cpu that has support for those.
