DESCRIPTION="
An i586 board, such as the original Pentium/Pentium Pro/Pentium II/Via Samuel

This demonstrates how creating code which runs on the host can still be cross
compiling, because the target may only support a subset of the host's
instruction set.  Thus target code runs on the host, but host code won't
run on the target, so you still can't afford to leak context.
