Log Message:
Disable SSE2 support for NetBSD-*-x86_64. This prevents segfaults under
NetBSD/amd64 5.1_STABLE. Bump package revision because of this change.

It is possible that SSE2 support works fine if "pixman" is built with
NetBSD-current's newer toolchain. If you have such a setup please
test it and adjust the package accordingly if appropriate.
