* configure.in: Remove check for -lintl (Bug#9713).

The check breaks 'configure' in some CentOS 5.7 x86 configurations.
The check was helpful but not essential in Solaris 2.6 (1997),
and is no longer needed in Solaris 8 (2000).  Solaris 2.6 is
obsolete -- Sun dropped support for it in 2006 -- and without
access to that Silurian platform we can't maintain the code anyway.
