--- Comment #1 from ma.jiang at zte dot com.cn ---
I encountered this bug some days ago when using lto. The compiler build a lot
of  symbols  like .LTHUNKxxx.xxx, some of them became undefined because of this
bug. And finally, I could not get my executable(although everythis is ok in
fact)...
The _bfd_elf_section_already_linked should not drop alreay_linked sections
simply.Relocating symbols to previous linked sections is also its
responsiblity.
