Fix configure to compile on i386.

We are carrying a patch for configure to include -li386 on i386/i486,
but the upstream script is missing the [] intended to match multiple
subfamilies, and hence does not match.  This commit just adds in the
missing [], enabling compilation to succeed on i386, and not changing
anything on !i386.
