[svn-r10070] Purpose:  Bug fix

Description:  On some Cray, the size of "short" is 8 byte but only the low-order 4 byte
are over used(precision is 4 byte).  The "perm" in struct "detect_t" contains "-1" for
bytes that aren't used, making detection of order invalid in function print_results().

Solution: Use a "for" loop to search through "perm" find the first non "-1" element,
and use it to decide the byte order of the machine.

Platforms tested: fuss - already tested for v1.6
