[committed] Fix warnings building trunk on vax-ultrix

["John David Anglin" <dave at hiauly1 dot hia dot nrc dot ca>]

This patch fixes a warning and two build failures in the vax backend.

One build failure was a typo.  "urem" was inadvertantly changed to "umod".
The other build failure was resolved by including toplev.h to resolve
the define for TARGET_OPTIONS.
