The patch applies cleanly to the 4.9-branch.

However, I am probably missing something since with an updated 4.9-branch and
without this patch, I couldn't make the compiler crash:
$ aarch64-unknown-linux-gnu-gcc -S test.c -mbig-endian
test.c:2:15: error: expected specifier-qualifier-list before âv4siâ
 struct S2823 {v4si a;int b[0];};
