#     kbuild: add -fcf-protection=none when using retpoline flags
#     
#     The gcc -fcf-protection=branch option is not compatible with
#     -mindirect-branch=thunk-extern. The latter is used when
#     CONFIG_RETPOLINE is selected, and this will fail to build with
#     a gcc which has -fcf-protection=branch enabled by default. Adding
#     -fcf-protection=none when building with retpoline enabled
#     prevents such build failures.
