That depends on the sysdeps Implies file. For i686, it uses i386/i486 but
*not* i386/i586.
(i586 uses i486, so any files for plain i386 that are overridden for i486,
or overridden for both i586 and i686, are dead and can be removed. It
would also be OK to merge i486 into i386 now anything before i486 isn't
supported.)
