If the TODO that is mentioned in r17516 would be fixed, would that help
that problem in any way? I, personally, don't use the concept of a board
in the context of buildroot. Put that aside, what about this layout:
-) same for build_
-) board_<device> as default COPY_TO
$device is target/device/*
$arch would be generic arch e.g. i386, arm
$subarch is the real -march=
$cpu is the real -mtune=
PS: r17516 was, for your convenience:
