I also like this feature very much!
However, I don't like at all the approach of passing the custom -I and -L
flags. I think it's much better to start with something that was suggested
before in the BR developer meeting: use the toolchain wrapper also for the
internal toolchain. Then we can pass the per-package staging dir through the
environment, and use it in the --sysroot argument of the compiler.
We'll also have to do something about ccache then - that could be a problem.
Perhaps ccache should be called from within the wrapper as well, that may solve
a bunch of other ccache problems.
