description:
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.
