Somewhere between precise and development upstream changed the order in which the tests are performed and triggered us to start linking against it again. = SRU Justification (for Artful/Xenial) = Impact: Linking perf (part of the linux-tools package) against libbfd prevents users to have linux-tools of different kernel versions installed in parallel. Which makes debugging hard. Fix: As stated above this had been fixed before but upstream changes of the kernel between 3.2 and 4.4 voided those fixes. Unfortunately without causing build failures but causing libbfd to be used again. This has already been fixed up in Bionic. The first of the two patches needs a backport for Xenial to make up for a file rename. The second can be picked into both releases. Testcase: Extracting ./usr/lib/linux-tools-*/perf from the generated linux-tools package and inspecting it with ldd. Old builds will have a reference to libbfd, the test builds did no longer. Risk of regression: low (change of build option which has been done before and also for some time in Bionic).
