Please help testing dropping a.out support from aboot

Upstream linux kernel has deprecated a.out object format a while ago.
However aboot tool still has support for it, which is keeping a.out.h
header in the linux kernel.
I'm trying to remove it, but to achieve this somebody needs to test
that upgraded aboot still works.

See details at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1059870

And https://lore.kernel.org/all/[email protected]/

I have ported objstrip.c to require ELF format kernel, and drop a.out
format kernel, but I have no way to test this.
