kbuild: move RETPOLINE flags below config-targets
When you run a "make *config" target, the retpoline compiler flags are evaluated for nothing because the code is located above the 'ifeq ($(config-targets),1)'. Move it a bit below to avoid unneeded computation in the Kconfig stage. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
