+perl sets C<$^X> where possible to a full path by asking the operating

+C<sysctl> with C<KERN_PROC_PATHNAME> if that is supported, else by reading

 (see http://www.freebsd.org/cgi/query-pr.cgi?pr=35703 ).
 In these cases perl will fall back to the old behaviour of using C's
 argv[0] value for C<$^X>.
