You're correct
(I'm not sure I have all the use cases for listing architectures in
control versus listing packages in P-a-s)

I'd expect so, but I didn't try; I don't see what floating-pointish
bits there would be in kexec, and the syscalls aren't impacted by this
ABI change. Let's find out! :-)

Makes sense, and an option I've left to the maintainer; that said I
think the P-a-s entry should be removed in any case.

Yup, I've done so when I thought the logs were relevant, but the rtai
is 100% sure due to my hardware and the slicer one is a 404 when
downloading a build-dep which seems like a debian-ports screwage that I
poked Konstantinos about.

Indeed, there's currently no mean to select between the two ABIs, and
only ARMv4 code is generated using either VFP or no VFP and using EABI
calling conventions or old ABI -- depending on which features were
present on the buildd.
I guess tcc should be fixed to allow selecting the ABI at runtime;
I've filed a bug against tcc to track this (bug id pending)

Makes sense to me
