This changes the installed file "scripts/Makefile.build" and causes build failures of dkms modules due to not found command "./debian/scripts/retpoline-extract-one"

There is a patch: https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/unstable/commit/?id=7c833a7bd411805861b77af148cb2fc30e429210

But it did not solve the problem for me.
If I build via "make-kpkg", then the debian/rules gets overwritten which contains the patch.

Building just with "make bindeb-pkg" doesn't work either, because the debian/rules is not called.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-trusty' to 'verification-done-trusty'. If the problem still exists, change the tag 'verification-needed-trusty' to 'verification-failed-trusty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
