Subject: [PATCH] Drop ELF notes from non-EFI binary too
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The ELF is repacked from from 64bit to 32bit. With CET-related notes,
which use 64bit fields, this results in 32bit binary with corrupted
notes. Drop them all (except build-id and PVH note retained
explicitly).
