I am not here to judge how protected symbols should be used. I don't
see gABI mention there is any limitation on protected symbols. We
didn't realize that we don't correctly handle protected symbols with
copy relocation until very recently. Since the i386 psABI predates
the current gABI, I have no problem with such a limitation and to
warn users about it.
