Found what might lead to the references I need:
http://www.mips.com/products/processors/32-64-bit-cores/mips32-24k/index.cfm#specifications

Which immediately shows that I made an error - about mid-page;
Just because the core has "core extend" does not mean it has 
hardware floating point.
duh...
It would seem that if you have enough gates for a pair of DSP
cores, you would have enough to "waste" a few thousand on H.F.P.

I'll dig into the problem and try to sort it all out today.
Will also try to figure out why I didn't get a backtrace from
a NaN error in Lua.  The "no backtrace" is a separate problem
from "no double" number type.

At first glance, it looks like a case for a Config.in.mips sub-menu.
Just to get all of the gcc options and core options to match up.
