I don't have time to search for them right now, so just a few:
gcc (e.g. libstdc++-v3, libgomp, etc. in it)
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.
