Gabriel F. T. Gomes 43257c335a Use TEST_COMPARE_STRING in recently added test

    support: Implement TEST_COMPARE_STRING

added the new macro TEST_COMPARE_STRING, which compares the output of
functions under test against expected strings, and, when there's a
mismatch, automatically reports an error and prints the differences.
This patch adapts recently added test cases to use this new macro.

Tested for powerpc64le (as is, and locally patched to intentionally fail
and produce error output).

	* argp/tst-ldbl-argp.c (do_one_test): Use TEST_COMPARE_STRING,
	instead of manually comparing and reporting mismatching strings.
	* misc/tst-ldbl-error.c (do_one_test): Likewise.
	* misc/tst-ldbl-warn.c (do_one_test): Likewise.
