objtool: Fix ".cold" section suffix check for newer versions of GCC
With my version of GCC 9.3.1 the ".cold" subfunctions no longer have a numbered suffix, so the trailing period is no longer there. Presumably this doesn't yet trigger a user-visible bug since most of the subfunction detection logic is duplicated. I only found it when testing vmlinux.o validation. Fixes: 54262aa28301 ("objtool: Fix sibling call detection") Signed-off-by: Josh Poimboeuf <jpoimboe@redhat.com> Link: https://lore.kernel.org/r/ca0b5a57f08a2fbb48538dd915cc253b5edabb40.1611263461.git.jpoimboe@redhat.com
