I was thinking that we could determine what the lowest-supported
architecture was for each version of Solaris, and that would be the
ISA that would be passed as -xarch. (Having an override would be fine,
but I'm wholly against the building of non-portable binaries by default.)

I have no idea how to determine what the least supported arch is for
each version of Solaris, though.
