[Buildroot] [PATXH v3 0/2] Update Xen and fix build issue

[Alistair Francis]

This patch series updates Xen to 4.7.1 and fixes a build issue that previously existed.

NOTE: Xen 4.8.0 was released today, but that failed to compile so it will be more work.
At the moment Xen doesn't build so fix that first.

V3:
 - Add a link to an autobuilder issue
V2:
 - Fix typo and add commit message to patch 2

[Buildroot] [PATXH v3 2/2] package/xen: Disable strict unused-const-variable checking

[Alistair Francis]

The strict unused-const-variable checking was causing autobuilder errors
when trying to build Xen tools/libxl as the migrate_*[] arrays are not
always accessed.

To avoid the error edit the Makefile to stop the warnings being treated
as errors.

Fixes:

Sorry for not catching this earlier, but what we want instead is to
completely remove -Werror. It's pointless for releases, and is causing
to cause other build failures.

Thanks,

Thomas

No worries, I have removed the -Werror. I left the other ones in there though.
