description:
Reapply fix for big-endian environments, which was lost when GSoC results
were merged...

http://www.nerv.org/netbsd/?q=id:20200620T075016Z.3584036ccf31f69ee76ea4a02e9be30ff081df21

> Fix false positive for mvscanw tests on big endian machines.
>
> When conversion specifier is not a derivative form of "%s", retrieve
> input as 32bit integer, and then convert to string literal. Then we
> can avoid interpretation from ASCII code to integer, which is
> apparently byte-order depended.
