Subject: [PATCH] kbuild: add -Wvla flag unconditionally
Date: Thu,  9 May 2019 15:45:49 +0900	[thread overview]
Message-ID: <20190509064549.1302-1-yamada.masahiro@socionext.com> (raw)

This flag is documented in the GCC 4.6 manual, and recognized by
Clang as well. Let's rip off the cc-option switch.
