Why is the binary target name being used for the package name? That's 
not intuitive to an end user at all IMHO.

I think confusing the binary target name with the actual package name is 
a mistake.

gcc is gcc, not i386-redhat-linux-gcc

OpenSUSE uses cross-<arch>-gcc/binutils/whatever-version
debian looks like it uses gcc/binutils/whatever-<arch>-version

Personally I like the cross-prefix, its a lot more obvious to an end 
user what the package is and is for, but thats just me.
