'make distclean' and 'make mrproper' should delete ALL intermediate build
files and basically return the local git repository to the same state that
it would be in if you did a fresh git-clone regardless of what config
options git set. So if one does:

make board_x-config
make all
cp u-boot.bin <somewhere>
make board_y-config
make all
cp u-boot.bin <somewhere else>
make mrproper

nothing should be left over from the build of 'board_x', even if it is a
completely different arch that 'board_y'

The list of files to delete should be in the board_x and board_y config.mk
files. Similiarly for arches and SoCs
