This has been triggered by the following commit:


commit 0e461945f3504e09b8ecf947b6398adce1287a28
Author: Masahiro Yamada <yamada.masahiro@socionext.com>
Date: Mon May 28 18:22:07 2018 +0900

gcc-plugins: allow to enable GCC_PLUGINS for COMPILE_TEST



CONFIG_GCC_PLUGIN_STRUCTLEAK_BYREF_ALL was previously disabled
for COMPILE_TEST, which is now enabled.



COMPILE_TEST now enables GCC plugin for wider test coverage,
this is a good thing in general.
