ok. I couldn't figure how to make bfd_coff_long_filename visible in the
linker, without #including libcoff.h, which seemed bad. As you can see
I just predicate the truncation check on bfd_family_coff.

Users have been customed to having --split-by-reloc in their make
files. We should either disable the option for elf, or make it work.
