If you can confirm that they have the right effect and put a signed-off + description to the patch, I'll merge it. Thanks, Jan

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. r~

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. Chris
