[PATCH v3 2/7] Prepare the manual to display math errors for float128 functions

["Gabriel F. T. Gomes" <gftg at linux dot vnet dot ibm dot com>]

New since v2:

  - This patch has been split from the last patch in this set, because it
    isn't powerpc64le-specific.

-- 8< --
When float128 support gets enabled for powerpc64le, the ULP errors for
float128 functions need to be presented in the manual.  This patch adds
support for displaying them.

Tested for powerpc64le and s390x.

	* manual/libm-err-tab.pl (@all_floats, %suffices, parse_ulps):
	Enable generation of float128 entries on the error table.
