Apparently, if you build a kernel for other than i386 (say, i486), it
won't run on i386

Well, I was experimenting with builing packages from source and I noticed
that they were compiled for i486. The rules file calls
to determine the machine.
I wondered why it sees my i586 as a i486.
Don't confuse this with the architecture which is i386, even for PentiumII
$ dpkg --print-gnu-build-architecture
$ dpkg --print-architecture
$ dpkg --print-installation-architecture
