I'm curious about this bit more than the generic gcc+FP issues.  I'm
using a "MKSOFTFLOAT=yes" built world on my walnut and haven't noticed
anything wrong in day-to-day usage.  Could you please give some details
on what bugs you've seen (and the fixes you have!), and also describe
``Until the "soft-float" options work altogether properly for powerpc''?

From a toolchain POV, the biggest problem is no way of identifying
soft-float objects from hard-float objects.  This pretty much
means that I've had to be careful with package builds, but keeping
"MKSOFTFLOAT=yes" in /etc/mk.conf helps.  This is something I keep
meaning to look at one day, but still haven't gotten around to.
The fact that there appears to be no powerpc elf supplement owner
didn't help :-(
