elf: Support DT_RELR in linker tests

Allow eabling and disabling DT_RELR in linker tests.  Disable DT_RELR in
linker tests which don't expect DT_RELR in linker outputs.

binutils/

	* testsuite/lib/binutils-common.exp (run_dump_test): Make
	DT_RELR_LDFLAGS and NO_DT_RELR_LDFLAGS global.

ld/

	* testsuite/config/default.exp (DT_RELR_LDFLAGS): New.
	(DT_RELR_CC_LDFLAGS): Likewise.
	(NO_DT_RELR_LDFLAGS): Likewise.
	(NO_DT_RELR_CC_LDFLAGS): Likewise.

	linker for some tests.
