I understand that it may be difficult to fix this in a way the binutils
maintainers will accept, but in your own words (from that thread), the
alternative of fixing it in GRUB is a workaround.

GRUB (and specially this part of GRUB) is very constrained in size.  A few
bytes can make the difference between safely embedding core.img in the post-MBR
area or jumping directly to a hard-coded offset in your filesystem.  I think
you should really try either fixing BFD or working around the problem somewhere
else (the runtime ELF loader seems like the worst of all the options to me).
