The problem, actually, is more complicated. Our architecture has non-unified memory.  Different  memories have different memory word sizes. When assembler sees instruction like this:
ld $r1, label + 5
it does not know in which section symbol is defined (section corresponds to memory type) and creates "generic" data relocation. In this  implementation  I suppose  that both addend  and  relocation address are  in  words.
I, probably, can implement this approach with with modified bfd_arch_mach_octets_per_byte() if "current" section is available. Does linker have interface to access "current" section?

Thanks,
