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

commit d658ddcc389085970ac025414cae7ad908f40726

    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.

	PR ld/28264
	PR ld/34572
	* testsuite/ld-plugin/dummy-elf.s: New file.
	* testsuite/ld-plugin/dummy.s: Revert commit d658ddcc389.
	* testsuite/ld-plugin/lto.exp (dummy_s): New.
	Build pr28264.so only for ELF targets.
	Replace "{dummy.s}" with "[list $dummy_s]".
