Well, the following sets it for Irix.  I'm only using Irix 6.2 and only
(very) remotely, and I didn't see the bug, but I've reconfigured to check
this doesn't do anything obviously wrong.  Helmut, you'll probably need
this.

In my case, fear.  But given that the mechanism we have seems to work
seamlessly when it's required, there's certainly an argument for removing
the test.

I also rescued Reliant UNIX and Rhapsody (see 4594) from the old
config.guess.
