Gabriel F. T. Gomes June 21, 2018, 2:10 a.m. UTC
Add tests for the functions from err.h and error.h that can take
positional long double parameters.  Most of the functions tested by this
patch do not return, so each have an independent test.

Tested for powerpc64le.

	* sysdeps/ieee754/ldbl-128ibm-compat/Makefile
	(tests-internal): Add test-warn-ibm128, test-warn-ieee128,
	test-err-ibm128, test-err-ieee128, test-errx-ibm128,
	test-errx-ieee128, test-verr-ibm128, test-verr-ieee128,
	test-verrx-ibm128, test-verrx-ieee128, test-error1-ibm128,
	test-error1-ieee128, test-error2-ibm128, and test-error2-ieee128.
	(CFLAGS-test-err-ieee128.c): New variable.
