_bfd_elf_gc_mark_rsec has
if (start_stop != NULL)
{
/* To work around a glibc bug, mark all XXX input sections
when there is an as yet undefined reference to __start_XXX
or __stop_XXX symbols. The linker will later define such
symbols for orphan input sections that have a name
representable as a C identifier. */
asection *s = _bfd_elf_is_start_stop (info, h);
if (s != NULL)
{
*start_stop = !s->gc_mark;
return s;
}
}
The question is if ELF linker automatically creates a definition when
there is a reference, regardless if the input section is orphan or not.
