[Xen-devel] xen/link: Move .data.rel.ro sections into .rodata for final link

[David Woodhouse <dwmw2@xxxxxxxxxxxxx>]

From: David Woodhouse <dwmw@xxxxxxxxxxxx>

This includes stuff lke the hypercall tables which we really want
to be read-only. And they were going into .data.read-mostly.

Signed-off-by: David Woodhouse <dwmw@xxxxxxxxxxxx>

Build tested on x86_64 (you really don't want to know about what I
*actually* tested it with), not at all tested on ARM.
