It's the doing-it-the-rpm-way that is a problem.  All from-scratch gcc 
cross compiler-generating scripts that I have seen require glibc sources 
as part of the compiler build.  In an rpm universe you only need headers 
and libraries to build a package, not sources from some other package. 
My scripts, Hans's scripts, and crosstool all have this limitation. 
This is because gcc contains both an independent compiler and 
libc-intertwined support libraries.

Doesn't seem like the sort of thing we could simply bolt onto the side 
of the existing build system and enjoy.  It's possibly not even that big 
of a change to the build system since it's just a slight twist on 
something it's already doing.
