Author: bdragon Date: Mon Jun 1 19:40:59 2020 New Revision: 361703 URL: https://svnweb.freebsd.org/changeset/base/361703 Log: [PowerPC] Fix build-id note on powerpc64 kernel Due to the ordering of the powerpc64 linker script, we were discarding all notes before emitting .note.gnu.build-id. This had the effect of generating an empty build id section and breaking the kern.build_id sysctl added in r348611. powerpc and powerpcspe are uneffected.
