[glibc/gabriel/powerpc-ieee128-printscan] ldbl-128ibm-compat: Add argp_error and argp_failure


https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=5e4992a36d45adb9fb21d1e99245ec811906db1a

commit 5e4992a36d45adb9fb21d1e99245ec811906db1a
Author: Gabriel F. T. Gomes <gabrielftg@linux.ibm.com>
Date:   Thu Jul 11 11:47:25 2019 -0300

    ldbl-128ibm-compat: Add argp_error and argp_failure
    
    Use the recently added, internal functions, __argp_error_internal and
    __argp_failure_internal, to provide argp_error and argp_failure that can
    take long double arguments with IEEE binary128 format on platforms where
    long double can also take double format or some non-IEEE format
    (currently, this means powerpc64le).
    
    Tested for powerpc64le.
    
    	* sysdeps/ieee754/ldbl-128ibm-compat/Makefile
    	[subdir == argp] (ldbl-extra-routines): Add argp-help.
    	[subdir == argp] ($(objpfx)tst-ieee128-argp.c)
    	($(objpfx)tst-ibm128-argp.c): New rule to copy the test from
    	the non-sysdeps directory to the build directory.
    	[subdir == argp] (tests-internal): Add tst-ieee128-argp,
    	tst-ibm128-argp.
    	[subdir == argp] (CFLAGS-tst-ieee128-argp.c): New variable.
    	[subdir == argp] (CFLAGS-tst-ibm128-argp.c): Likewise.
    	* sysdeps/ieee754/ldbl-128ibm-compat/Versions (libc): Add
    	__argp_errorieee128 and __argp_failureieee128.
    	* sysdeps/ieee754/ldbl-128ibm-compat/ieee128-argp-help.c: New file.
