Right.  So it looks like assuming that a kernel without relocations for the
__ksymtab is not sufficient to assume that the __ksymtab section is in the
v4.19 format, because there can be kernels built without relocation, e.g,
non-relocatable kernels.

So I wrote and checked in a new heuristic into the master branch of the git
repository at
https://sourceware.org/git/gitweb.cgi?p=libabigail.git;a=commit;h=f9b2f3751262f4695a46994b96b74a6a37419b54.

This should hopefully work better.

Thanks for following up on this and sorry again for the inconvenience.
