Not sure if this a toolchain bug or elfutils bug. readelf from
binutils prints GNU_UNIQUE.
If not obvious binutils/readelf.c contains:
if (binding == STB_GNU_UNIQUE
&& (elf_header.e_ident[EI_OSABI] == ELFOSABI_GNU
/* GNU is still using the default value 0. */
|| elf_header.e_ident[EI_OSABI] == ELFOSABI_NONE))
return "UNIQUE";
So I think this is a toolchain bug. It is nice of binutils to
accept STB_GNU_UNIQUE with the wrong EI_OSABI, but I don't think
you can rely on all tools being so lenient.
Okay, I'll try to figure what's special about the affected DSOs and
isolate the toolchain bug.
