-Subject: [RFC PATCH v4 2/2] MIPS: make FPU emulator optional

-This small patch makes the MIPS FPU emulator optional. The kernel
-kills float-users on systems without a hardware FPU by sending a SIGILL.
-
-Disabling the emulator shrinks vmlinux by about 54kBytes (32bit,
-optimizing for size).

----
-v4: rediffed because of patch 1/2, should now work with micromips as well
-v3: updated patch description with size savings.
-v2: incorporated changes suggested by Jonas Gorski
- force the fpu emulator on for micromips: relocating the parts
- of the mmips code in the emulator to other areas would be a
- much larger change; I went the cheap route instead with this.
