Because all the cross-compile makefiles, binutils/gcc/glibc configure script 
etc, expect it to be under $prefix/$target. Moving away from this will become a 
HUGE patchfest and then people will start complaining that app XXYZ doesn't 
work with our cross-compile toolchain because we did things different.

Besides that there are binaries installed under /usr/avr/bin, moving things to 
under /usr/share thus is not an option.

Also see the long list of rationale I gave in the original post, but you didn't 
bother to go into.
