Said library is *not* (per standard sources) linked with
the kernel. (At L-F-S work I am happy that it is *not*
linked in per default.)

That theory works only if you use non-standard image linking.

A comparison of produced binary object files when compiled
at the i686 vs. at the i486 would be most educative.

Which change, and in which manner. I presume the configuration
is identical in both cases ? What does command
egrep CONFIG_X86 .config
tell ?
