Subject: [PATCH 5.10 129/132] kbuild: simplify GCC_PLUGINS enablement in dummy-tools/gcc

From: Masahiro Yamada <masahiroy@...nel.org>

commit f4c3b83b75b91c5059726cb91e3165cc01764ce7 upstream.

With commit 1e860048c53e ("gcc-plugins: simplify GCC plugin-dev
capability test") applied, this hunk can be way simplified because
now scripts/gcc-plugins/Kconfig only checks plugin-version.h
