No need for that eithr. They can figure out

Isn't that easy, you'll have to do a bunch of fixups after doing so to
have things actually work. Also automagic fetching of packages
(including dependencies) would be nice. Upgrading them even nicer.
Creating a script (or yum plugin?) doing all that is probably *much*
less work than creating tons of extra packages for userspace cross builds.
