Subject: [PATCH] [AArch64] Fix build issue with aarch64-builtins.c on MacOS X
 host

When building w/clang on MacOS X we get the following error:

gcc/config/aarch64/aarch64-builtins.c:1231:3: error: expected expression
AARCH64_INIT_MEMTAG_BUILTINS_DECL (IRG, irg, irg, fntype);

Fix this by adding '-std=gnu++11' to the compile line.
