Re: aarch64: Add some DT_RELR ld tests

aarch64-elf fails these tests due to .rela.dyn being at a different
address to that expected, and due to the symbol table being different.
Unexpected symbol numbering results in a mismatch of reloc r_info
field, but these are shown decoded so the raw field doesn't really add
anything to the test.

	* testsuite/ld-aarch64/relr-align.d: Accept any address for
	.relr.dyn section.  Don't match raw r_info field.
	* testsuite/ld-aarch64/relr-data-shared.d: Likewise.
	* testsuite/ld-aarch64/relr-got-shared.d: Likewise.
	* testsuite/ld-aarch64/relr-text-shared.d: Likewise.
