The entire BR2_DEFCONFIG mechanism has never done what I expected.
What I want is that 'make savedefconfig' (or a similar command) saves
the configuration back to where it originated from. BR2_DEFCONFIG does
more or less that, but only if you set the configuration initially
with 'make defconfig BR2_DEFCONFIG=...' instead of the normal 'make
xxxx_defconfig'. Isn't this possible to achieve?

Best regards,
