ldbl-opt: Reuse test cases from misc/ that check long double
This patch adds test cases for the compatibility versions of the
functions: err, errx, verr, verrx, warn, warnx, vwarn, vwarnx (from
err.h), error, and error_at_line (from error.h), when long double has
the same format as double (-mlong-double-64).
Tested for powerpc, powerpc64 and powerpc64le.

ldbl-opt: Add error and error_at_line (bug 23984)
On platforms where long double may have the same format as double
(-mlong-double-64), error and error_at_line do not take that into
account and might produce wrong output if a long double conversion is
requested by the format string ('%Lf'). This patch adds compatibility
functions for this situation and redirects calls via header magic.
Tested for powerpc, powerpc64 and powerpc64le.

ldbl-opt: Add err, errx, verr, verrx, warn, warnx, vwarn, and vwarnx (bug
23984)
When support for long double format with 128-bits (-mlong-double-128)
was added for platforms where long double had the same format as double,
such as powerpc, compatibility versions for the functions listed in the
commit title were missed. Since the older format of long double can
still be used (with -mlong-double-64), using these functions with a
format string that requests the printing of long double variables will
produce wrong outputs.
This patch adds the missing compatibility functions and header magic to
redirect calls to them when -mlong-double-64 is in use.
Tested for powerpc, powerpc64 and powerpc64le.

ldbl-opt: Reuse argp tests that print long double
The test case tst-ldbl-argp checks that the conversion specifier '%Lf'
correctly prints long double values with the default long double format
for a platform. This patch reuses the test case for long double with
the same format as double (-mlong-double-64).
Tested for powerpc, powerpc64 and powerpc64le.

ldbl-opt: Add argp_error and argp_failure (bug 23983)
The functions argp_error and argp_failure are missing support for
printing long double values when long double has the same format as
double. This patch adds the new functions __nldbl_argp_error and
__nldbl_argp_failure, as well as header magic to redirect calls to them
when -mlong-double-64 is in use.
Tested for powerpc, powerpc64 and powerpc64le.
