It's needed by any system using a (logically) external FPU. If set it
means there is no need to install a special FPU exception handler using a
general-purpose interrupt line. It's a generic flag.
Even if it's only of limited use now, it is not an excuse for not writing
clean code. I'm afraid the current mess within the MIPS port is a result
of people trying to think locally and I'm trying to avoid it. Are there
any trade-offs of this flags you see and I don't? I'm willing to change
the code if there really are.
