[Xen-devel] [PATCH 1/2] build/clang: remove the address-of-packed-member warning

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

Clang 4.0 has added a new check that triggers when taking the address of a
field of a packed structure. I've explained our situation to the llvm/clang
folks, but nobody seem to care:

https://reviews.llvm.org/D20561

So simply disable that check if present.
