Problems building (anything)

[mike]

I have two machines with full build environments with FC3T1, the work
machine is fine (1400 duron)

However my home machine wont build anything, it bails with an error
"internal compiler error - illegal instruction"

As an example building the kernel, this occurs on make menuconfig on
scripts/basic/fixdep (ie immediately, so would not appear to any broken
hardware isues)

The only thing I can think of is that my home box is a K6/2 ie: i586
