linux-next: disabling -Wstringop-truncation

[Stephen Rothwell]

I am now mainly using gcc v8.2 for my builds and -Wstringop-truncation
causes so many warnings that I am sure to miss others, so I have
applied the below to my fixes tree until the noise reduces.

Subject: [PATCH] disable stringop truncation warnings for now
