Do not hardcode platform names in manual/libm-err-tab.pl (bug 14139).

Browse Source 
manual/libm-err-tab.pl hardcodes a list of names for particular
platforms (mapping from sysdeps directory name to friendly name for
the manual).  This goes against the principle of keeping information
about individual platforms in their corresponding sysdeps directory,
and the list is also very out-of-date regarding supported platforms
and their corresponding sysdeps directories.

This patch fixes this by adding a libm-test-ulps-name file alongside
each libm-test-ulps file.  The script then gets the friendly name from
that file, which is required to exist, so it no longer needs to allow
for the mapping being missing.

Tested for x86_64.

	[BZ #14139]
	* manual/libm-err-tab.pl (%pplatforms): Initialize to empty.
	(find_files): Obtain platform name from libm-test-ulps-name and
	store in %pplatforms.
	(canonicalize_platform): Remove.
	(print_platforms): Use $pplatforms directly.
	(by_platforms): Do not allow for platforms missing from
	%pplatforms.
