[AArch64-4.7] Backport: Fix g++.dg/abi/aarch64_guard1.C

[James Greenhalgh]

Hi,

If we enable section anchors by default we must fix the
ABI testcase which is not expecting section anchors.

This was fixed by Andrew Pinski on trunk here:
http://gcc.gnu.org/ml/gcc-patches/2012-11/msg00580.html
So we backport that fix.

I've tested this with no regressions on aarch64-none-elf.

Is this OK to commit to aarch64-4.7-branch?

Thanks,
James Greenhalgh
