When building with binutils-2.18, vmlinux includes .note.gnu.build-id sections that need to be stripped out when building the binary image. The old .xt.insn sections haven't been used for a long time, so don't bother stripping them. Signed-off-by: Bob Wilson <bob.wilson@acm.org> Signed-off-by: Chris Zankel <chris@zankel.net>
