I do not disagree, but I will note that some PPC systems have
hardware FPUs while others do not.  So binaries compiled with
floating-point support (the default) require the kernel FP
emulation, which will slow them down considerably on those
systems.

So for maximum compatibility, compile with -msoft-float.  If
you're only worried about 60x, 7xx, 7xxx, and 824x, CPUs, then
don't worry about it.  IBM 4xx, and Motorola PowerQUICC series
don't have FPUs.
