[Buildroot] [PATCH] buildroot:linux: Add options to checkout Linux kernel source from SVN or GIT repository.

Ok, I'm looking forward to it (and to the other one). The download
mechanism still has some shortcomings.

For keeping the version control information, this folds in the "doing
application development with Buildroot" process discussion, which we
should really get going to discuss this and come up with a reasonable
solution (Thomas? Peter? do you have any input on this?).

As for the Linux kernel, I am running into the same problem as well (not
only for the kernel, but for any non-package software like bootloaders),
so we need to find a common way of downloading sources from the web,
Svn, Git or whatever, being in the GENTARGETS infrastructure or not.
Here again, any input is most welcome so we can design the appropriate
solution (see my email on X-Loader support for a few more insights on
this).
