Disable spurious -Wstringop-overflow for setjmp/longjmp (bug 26647)

[Florian Weimer]

Why can't we do this instead, given that's an internal function?

- extern int __sigsetjmp (struct __jmp_buf_tag __env[1],
+ extern int __sigsetjmp (struct __jmp_buf_tag __env *,

Or doesn't this remove the warning?

Thanks,
Florian
