I've been follwing this thread with some interest but I still do not
quite understand the need for the $build variable (outside of Canadian
cross-compiling, that is).  In the Mozilla project, I chose to use $host
!= $target to be indicative of a cross-compiled build.  Because of
existing limitations, you also have to set CROSS_COMPILE=1 but that env
variable will go away when the limitations do.   When would it be valid
to have $host = $target and still be cross-compiling?
