Subject: [PATCH 3/9] rhel: Drop machine type pc-q35-rhel7.0.0

O-Subject: [PATCH RHEL-7.1 qemu-kvm 1/1] rhel: Drop machine type pc-q35-rhel7.0.0
Bugzilla: 1111107
RH-Acked-by: Laszlo Ersek <lersek@redhat.com>

Q35 is tech preview in RHEL 7.0.  From 7.1 on, we want to support it,
but only in qemu-kvm-rhev.  We don't intend to support it in qemu-kvm.
So as to not mislead customers, drop the machine type from qemu-kvm,
by removing pc_q35.c from the build.  Remove RHEL-specific code from
pc_q35.c just to avoid confusion.
