We've been playing a bit with kvm-kmod-3.0b.  We use a cross compile
environment, and one of my coworkers noticed that the variables in

effect.

Please elaborate on "no effect", and what actual problems you are
experiencing.  I do cross-compilation builds all the time and have
no such problems.

The behaviour I see is that I configure with --cross-prefix=<prefix> then the appropriate prefix gets set in config.mak. However, when running "make" the prefix doesn't actually get used.

If building for the same target as the host machine this isn't immediately obvious because it uses the host compiler. However, if you run "make V=1" it will show which compiler is being used.
