     I have now applied this change.
    
And I just checked the patch below to remove the objcopy workaround.

I think by now the two problems described in
https://sourceware.org/ml/binutils/2017-04/msg00264.html are fixed :)

    binutils: remove sparc64/mips64 workaround in objcopy build notes merge code
    
    This patch removes a workaround recently installed in objcopy that
    avoided removing duplicated notes in targets for which the number of
    internal relocations may be bigger than the number of external
    relocations.  With the recent fixes in sparc64 and mips64, this
    workaround is no longer necessary.
