i will answer the question myself: it is not.
defconfig must be called after working with 'menuconfig'.

maybe you have an idea, how we can speedup our workflow:


echo  >.config 'CONFIG_TARGET_ar71xx=y'
echo >>.config 'CONFIG_TARGET_ar71xx_generic=y'
make defconfig

(apply some symbols)
make defconfig

[...]

(apply some symbols)
make defconfig

This is called up to 30 times till our '.config' is ready.

Question: is it *safe* to call 'defconfig' only at there very end?
