So programs called from make will not receive a SIGPIPE when writing to a closed pipe but instead an EPIPE write error. `find` does not seem to handle this. This behavior in make is new and I can't find a reasoning for it. It also breaks other softwares builds. For now you can disable CONFIG_IKHEADERS and the build should work again. Thomas [0] make 4.4 was packaged for ArchLinux on 5th of January, so it would fit the timeline.
