Wei Liu ae05efd989 Config.mk: update OVMF changeset
Signed-off-by: Wei Liu <wei.liu2@citrix.com>
Acked-by: Ian Campbell <ian.campbell@citrix.com>

(cherry picked from commits 04c5efb0a1
 and f046e501bb)

Apropos of discussion in
 "OVMF related osstest failures on multiple branches"
 http://lists.xenproject.org/archives/html/xen-devel/2016-01/msg00442.html

We believe the older ovmf.git does not work when built with the gcc in
Debian jessie.  We do not know where this bug lies but we are fixing
it by updating ovmf.

We have decided that we are not in a position to review the changes to
OVMF upstream, and ourselves decide what to cherry pick.  Instead we
will update the revision wholesale and use the xen.git stable
branches' push gate.

In 4.3, old OVMF_UPSTREAM_REVISION was b0855f92 rather than cb9a7eba.
I have pulled in the additional changes, willy-nilly.

# cc-option: Check if compiler supports first option, else fall back to second.

# This is complicated by the fact that unrecognised -Wno-* options:
# (a) are ignored unless the compilation emits a warning; and
# (b) even then produce a warning rather than an error
# To handle this we do a test compile, passing the option-under-test, on a code
# fragment that will always produce a warning (integer assigned to pointer).
# We then grep for the option-under-test in the compiler's output, the presence
# of which would indicate an "unrecognized command-line option" warning/error.
