Hello.
We use the same approach where only a selected packages enable FAT lto objects.
You can take a look at our META bug where such packages are linked (in most
cases):
https://bugzilla.opensuse.org/show_bug.cgi?id=1133084
Or one can easily grep it from here:
https://github.com/bmwiedemann/openSUSE
$ git grep 'fat-lto-objects'
(see attachment)

We strip this way:
https://github.com/openSUSE/brp-check-suse/blob/2f7add6f0b7f5c2e9698d180a4761a10fb808482/brp-15-strip-debug#L38

And we integrated a rpmlint check that checks we don't ship a LTO bytecode:
https://github.com/rpm-software-management/rpmlint/blob/aa1f710c1b3ff409e42068c2b067ab2eee200b1d/rpmlint/checks/BinariesCheck.py#L277-L283
and there's one related check where we look if a static library contains
something:
https://github.com/rpm-software-management/rpmlint/blob/aa1f710c1b3ff409e42068c2b067ab2eee200b1d/rpmlint/checks/BinariesCheck.py#L230-L255
it can happen that it only contained bytecode that was eventually striped.
Cheers,
Martin
