I suspect that's more of an artifact than an actual decision.  Until
the actual work was done to allow G77 to play nice with multilibs there
wouldn't have been much motivation to add -mieee support.

Before we did the work, I remember it frequently coming up that the G77
crowd _wanted_ -mieee libraries - that was one motivation to do the
work.  I'm just guessing that now that the infrastructure is there that
nobody has "turned on" the missing bits.

It should border on trivial now but I don't know that I'd call it cookbook.

It's _probably_ about as simple as adding the appropriate MULTILIB_*
definitions in the tm.h for whatever target you're building.   There's 
probably some additional details to work out.

Pick a target that would benefit from this and I'll help you make it go.
From there perhaps we can derive a recepie.

"I don't know the recepie so we'll add stuff until it tastes right.
Then we write down the ratio of stuff that we added." 

Alternately, you can send me an Alpha. :-)
