I suppose I can tell since currently shipping 8260 come with FPU.
Early 8260 are just like the early 486SX - it does contain a FPU,
but it is disabled. But unlike the 486SX the 8260 FPU can be
reenabeled by some microcode patch - wich I do not have myself.
This is as much I know of this. If you are really nice to
Motorola then perhaps they will let you have this patch.

configure & make xgcc -nfp?
Then recompile GLibC (with soft float) I suppose.
