I don't think this is the way to do it. For those cases it is mandatory
that libc is actually using the PLT entry, so we don't want a check that
would pass if libc stopped using it at all. Perhaps instead there is a way
to modify scripts/localplt.awk and/or scripts/check-localplt.awk so that
they will grok the new linker's output as constituting use of a PLT entry.
Maybe a GLOB_DAT reloc to a symbol that's STT_FUNC is a close enough proxy?
