I don't have time to search for them right now, so just a few: gcc (e.g. libstdc++-v3, libgomp, etc. in it) glibc gmp openssl You are trying to make small differences in configure triplets irrelevant, but in reality sparc-linux is something different from sparcv9-linux from say sparcv9v-linux and i586-linux is different from i386-linux. If you omit --host and --build, config.guess will guess these from the build box and then you'll wonder why packages built on say SPARC Niagara don't work at all on older sparc64 boxes, eventhough the packages are still sparcv9.rpm and similarly in the i?86 world.
