Package: kicad Version: 5.1.4+dfsg1-2 Upstream had replaced boost::context to a built-in libcontext library in https://bugs.launchpad.net/kicad/+bug/1658249, so libboost-context in dependency should be dropped.
Also, after we upgrade to GLM-0.9.9.6 in sid, GCC build is possible again, thus clang is no longer required too. After drop these two dependencies, we can now trigger a success build on mips64el platform.
