Is it possible to "fix" this (ie, provide ABI compatible versions for
i386 and i486) without breaking stuff? 386s are faster than many other
pieces of hardware that we still support, so dropping them seems strange
- on the other hand, an i386 sub-distribution sounds like a world of
pain. Having a standard library that only supports one of the allegedly
supported processors if the ABI changes sounds like the real bug to me.
