This resolves the build issue with building the ROMs on OpenBSD on x86 archs. As of OpenBSD 5.3 the compiler builds PIE binaries by default and thus the whole OS/packages and so forth. The ROMs need to have PIE disabled. Check in configure whether the compiler supports the flags for disabling PIE, and if it does then use them for building the ROMs. This fixes the following buildbot failure: >From the OpenBSD buildbots..
