Subject: gcc: add build fix for aarch64 toolchain on MacOS X

When building aarch64-unknown-linux-gnu on MacOS X, aarch64-builtins.c
files doesn't build by default with clang on MacOS X.  We need to pass
-std=gnu++11 when building the file for things to work with clang.

+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.
