Details:
As outlined in
http://www.mikrocontroller.net/topic/236837#2402619
the search policy for the build compiler has to be checkes:
1) CC
2) --prefix
3) PATH
Moreover there is a proposed patch
* configure.ac (CC): Use `${CC} -dumpmachine` to query for
right cross compiler instead of checking CC.
