I think INT is preffered over SIGINT.
You may also add QUIT and TERM.
With QUIT, you can replace cleanup_and_exit calls by a simple exit.

May be simpler "git log -1 --format=%H"

I think it may be removed as no app is run.

So you prefer modifying defconfig instead of .config, right?
(you sent it while I was answering on v2)

Already exported.

Could be OLDNAME=$(basename $i 1.dump)0.dump

Could be LIBNAME=$(basename $i -ABI-1.dump)

Thanks
