    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.
