+Subject: objtool: Clobber user CFLAGS variable
+
+From: Josh Poimboeuf <jpoimboe@redhat.com>
+
+commit f73b3cc39c84220e6dccd463b5c8279b03514646 upstream.
+
+If the build user has the CFLAGS variable set in their environment,
+objtool blindly appends to it, which can cause unexpected behavior.
+
+Clobber CFLAGS to ensure consistent objtool compilation behavior.
