Add ARM auditing support

- Subject: Add ARM auditing support
This patch, with my previous patch for the architecture-independent bits,
allows tst-audit1 to pass for arm-none-linux-gnu. This is the first of
three ARM patches needed to build HEAD glibc.
OK to apply?
Phil, for now I'm going to assume you'd still prefer to approve ARM patches.
If you'd rather I just applied them myself, let me know.
