[PATCH 3/3] kbuild: add -Wno-unused-but-set-variable compiler flag unconditionally

From: Masahiro Yamada
Date: Mon Oct 01 2018 - 05:45:31 EST


We have raised the compiler requirement from time to time.
With commit cafa0010cd51 ("Raise the minimum required gcc version
to 4.6"), the minimum for GCC is 4.6 now.

This flag was added by GCC 4.6, and it is recognized by Clang and
ICC as well.

Let's rip off the cc-disable-warning switch, and see if somebody
complains about it.
