This patch adds the Aarch64 SVE specific HWCAP_SVE define.
The Linux kernel changes for Aaarch64 SVE have recently been pulled
into the head:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c9b012e5f4a1d01dfa8abc6318211a67ba7d5db2
Although not due to be in a kernel release until early 2018, we'd
like to make sure any newlib changes are ready for a similar time.
I haven't run any testsuites as the changes are should not effect them.
Is this ok?
Thanks,
Alan.
