This has bothered me as well. I would like to see a few machines added
at least something like R5000, R8000, R10000 along with the proper ISA
value being stored in the e_flags field. I would be more than happy to
help make the changes as it is something that IMHO needs to be fixed.

As far as the latest ABI specs go, here are 2 different links for the
same documents. Ralf and I went digging for these a few weeks back.
