Comment # 4 on bug 953297 from Josef M�llers

I discussed this with one of the maintainers of grub2 and he corrected me:
while the packages do contain machine-specific code, they are not "machine
specific" like are other packages as the code is not used under Linux and so
should be treaded as "data".
Thus said, there are, however, some issues wrt the build and upgrade processes
that need to be addressed and which may, eventually, prohibit the change to
"noarch". But, as I said, I stand corrected and see what I can do.
