By "this" I assume you mean using the external config-bisect code,
rather than the part about copying oldconfig output?

The options I can see are to copy both files as a group (possibly making
that easier by renaming config-bisect.pl to ktest-conf-bisect.pl, so you
can "cp tools/testing/ktest/ktest*.pl <dest>"), or just living with code
duplication.  In a previous discussion you suggested you preferred that
latter option, though in that case the config bisect logic changes
should ideally be done before the fork.

It should also be noted that ktest.pl only depends on config-bisect.pl
if a config bisect is being performed, so other ktest.pl functions still
work standalone.
