Re: readelf: Add --got-contents option

The cris ld testsuite uses readelf -a.  The extra output now means
that a number of tests fail.  Fix that by not using -a, but rather
the options corresponding to output checked in the dump files.

	* testsuite/ld-cris/tls-local-63.d: Replace -a option with -r -s.
	Remove now unnecessary #... and superfluous unwind message.
	* testsuite/ld-cris/tls-local-64.d: Likewise.
	* testsuite/ld-cris/tls-und-38.d: Likewise.
	* testsuite/ld-cris/tls-und-42.d: Likewise.
	* testsuite/ld-cris/tls-und-46.d: Likewise.
	* testsuite/ld-cris/tls-und-50.d: Likewise.
	* testsuite/ld-cris/weakref3.d: Replace -a with -S -r -s, and
	remove unwind message.
	* testsuite/ld-cris/weakref4.d: Likewise.
