[LEDE-DEV] LEDE builds kernel from scratch after minor changes

[Rafał Miłecki]

I got used to doing some small target modifications, calling "make
V=s" and getting new image quickly build.

>From some time (less than a month I think) modifying e.g.
target/linux/bcm53xx/base-files/etc/board.d/02_network
and calling "make V=s" results in cleaning and rebuilding whole kernel.

I think it also happens after changing config with "make kernel_menuconfig".

Is this intentional? Could LEDE building system be improved to e.g.
react only to kernel patches changes?
