[Qemu-devel] [PULL 10/10] build-sys: restrict vmcoreinfo to fw_cfg+dma capable targets

["Michael S. Tsirkin" <mst@redhat.com>]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

vmcoreinfo is built for all targets. However, it requires fw_cfg with
DMA operations support (write operation). Restrict vmcoreinfo exposure
to architectures that are supporting FW_CFG_DMA, that is arm-virt and
x86 only atm.
