Indeed.

Yeah, I just saw that this makes much more sense for grub, as you need 
the package for both architectures (right now, we actually change a 
comment everytime we build it). However, my motivation was that right 
now I am building some multilib stuff and have packages that always have 
to be built on i686 and installed on x86_64. So at the end of the 
build() procedure I need to do 'export CARCH="x86_64"', which is a hack 
that doesn't work with -L for example.

Using a -D option would mean that I have to build 20 or 30 packages with 
'-D x86_64' all the time. My goal was to make the build procedure for 
these packages intuitive enough, so you can't build them "wrong".
