Actually I've thought about the toolchain thing a little more and I have
an idea: make it possible for the SDK to use an Openwrt Toolchain
tarball as the toolchain, and don't ship the binary toolchain as part of
the SDK at all.
One possible improvement would be for the binary toolchain to also
include relevant host tools, and not be strictly the compile toolchain.

Hi Felix,
I've been thinking about the sourceful SDK and have some ideas on how to
implement, I just want to clarify one point:
Are you thinking the SDK should be like the buildroot where everything
(including tools and toolchain) is built from source, or are you
thinking tools and toolchain (but not kernel, because that introduces
build_dir/staging_dir messiness) should be precompiled (so that the rest
may be compiled without much in the way of external dependencies).
I'm actually think OpenWrt's build dependencies are light enough that it
might make sense to do an entirely sourceful SDK, and completely skip
pacakaging binaries (except for the option of downloading and including
source archives).
With your recent target/linux commit this shouldn't cause any major
headaches, and the SDK can already generate the Config.in placeholders
that make sure both the base system and SDK are configured with the same
settings (e.g for kernel compile).
Actually I have to review the SDK and figure out why the kernel is in
the SDK in the first place (ImageBuilder those binaries are obviously
required, but the SDK I'm not sure why they're there, or if I'm actually
misremembering and there is no kernel in the SDK; if that is the case
then the whole thing gets a lot easier).
Regards,
Daniel
