--- Comment #1 from vijay Shankar <shank.vijay at yandex dot com> ---
I have a patch suggestion for this issue
added check to copy_private_bfd_data so that sections with inconsistent
relation between vma and lma go to re-write im not sure how this will affect
other cases maybe linker scripts? waiting on experts opinion on this change.
alternative way would be to exclude tbss from PT_LOAD by adding checks in
releavent places ( ELF_SECTION_IN_SEGMENT_1, make_mapping ).
