Hi Thomas,

I agree on the first one that it is not neccessarily limited to the ARM
Could be used at any time when compiling a kernel in general.

Concerning native config:
When you have a look at the Zedboard or the Raspberry Pi there are already
modified kernel sources fitting to the board.
In some cases this is not enough for the requirements of oneself and you start
tweaking it. This is the point where you start "branching" the project and
saving ( mostly likely ) the config related to your changes. Of course, you
host this branch on a server and to make life easier for other developers you
provide an out of the box solution. I know I could easily use
"$(LINUX_DIR)/.config" as config file path but I though it was worth a single
