Yes, --disable-gcov does help as well. I just wasn't sure whether having gcov support might make sense on a cross-compiler or not, and as the FreeBSD port did have it enabled before, I was merely tempted to do it that way. But yes, it's probably questionable whether anyone would really run gcov on an AVR. ;-)
