Function symbols of course don't normally want .dynbss copies but with some old versions of gcc they are needed to copy the function descriptor. This patch restricts the cases where they are useful to compilers using dot-symbols, and enables the warning regardless of whether a PLT entry is emitted in the executable. PLTs in shared libraries are affected by a .dynbss copy in the executable. bfd/ PR 25384 * elf64-ppc.c (ELIMINATE_COPY_RELOCS): Update comment.
