I want to rename my kernel image from `bzImage` to anything else.
But it is so tiresome to do that every time I do `make`.
I think it is possible if `post-world-hook` or `post-all-hook` is provided by
board specific makefiles.

My suggestion is like below:
- In this case, I use `board/sample/linux-2.6.37.config` as kernel config.
  (BR2_LINUX_KERNEL_CUSTOM_CONFIG_FILE=board/sample/linux-2.6.37.config)
