(bfd_elf_gc_sections): Fail if a shared object is being created.
Do not fail if dynamic sections have been created. Instead call
elf_gc_mark_dynamic_ref_symbol to mark sections that contain
dynamically referenced symbols. Do not mark the whole graph
rooted at .eh_frame, only the section proper.
type and size change code to where it was previously. Remove
dt_needed param. Treat old weak syms as strong if new sym is
from a shared lib, even when old sym is from another shared
lib. Remove unnecessary tests of oldweak and newweak. Correct
comments.
