I probably don't know all the issues.  But BFD already supports
multiple sections with the same name.  The problem is that the ELF
backend always calls subseg_new() in obj_elf_change_section().

If there is a group, you could change obj_elf_change_section() to look
through the sections using bfd_get_section_by_name().  If the section
does not already exist with the right group, then
obj_elf_change_section() would call subseg_force_new() rather than
subseg_new().  Otherwise obj_elf_change_section() would call
subseg_set() with the right section.

There are probably some incorrect details.  But it seems to me that
that general approach ought to work.
