This patch was merged, but I frankly don't like what it does.
Building in a separate dir is fine, but it does so with a bunch of changes along that introduce indenting errors and potentially destroy the scripts' certainty of building cleanly every time.
Please still reply to my comments at https://gerrit.osmocom.org/#/c/3132/
...maybe actually here on the ML instead of on gerrit?
Thanks!
