Now that the kernel-image packages supports hw emulation of i486 instructions on i386 hardware, I'd like to change the code generation to default to i486 (not sure if it should be tuned for any other target, i.e. -mtune=i686).
IIRC the Hurd can be built for i586 only, so it could be used as the default target CPU as well. Unsure about the bsd targets. Matthias
