So with this patch, passing PATH in all the package infrastructures
(cmake, autotools, python) becomes unnecessary?

I must say I am not entirely sure we want to globally export PATH.
Packages using custom build system should use TARGET_MAKE_ENV and
HOST_MAKE_ENV, post-build and post-image script have HOST_DIR defined
in their environment I believe.

But this is not a strong opinion, I'd just like to see
arguments/opinions from others on this specific change (the other
changes in the series, I'm happy with them on the principle, they are
just a few remaining details to sort out).
