    ld: Replace "{dummy.s}" with "[list $dummy_s]"

        lto: Don't check format of IR dummy file
    
    added
    
            .section .note.GNU-stack,"",%progbits
    
    to testsuite/ld-plugin/dummy.s for PR ld/34572 tests with Clang.  But
    it doesn't work for non-ELF targets.  Add dummy-elf.s and restore the
    previous dummy.s.  Define dummy_s to dummy-elf.s for ELF targets and to
    dummy.s for non-ELF targets.  Replace "{dummy.s}" with "[list $dummy_s]".
    Also build pr28264.so only for ELF targets since it uses readelf.
