Hello!

Starting with version 27, Emacs has started failing to build from source
on m68k (Linux) with the following error message:

dump relocation out of range

Full build log available in [1].

I have not been able to figure out what "dump relocation out of range"
actually means, so any explanation is much appreciated.

Thanks,
Adrian
