[Patch docs obvious] install.texi: Put aarch64 back in alphabetical order, add link


Hi,

Looking at https://gcc.gnu.org/install/specific.html , aarch64*-*-* is
in an odd place and isn't linked to from the top of the file.

This patch fixes that by reordering the entries and adding a link
from the menu at the top of the page.

I've built the documentation with no new issues, and had a look in
firefox to ensure the changes were sane.

I've applied this patch under the obvious rule as revision r220738.

Thanks,
James
