I don't know what iPXE uses syslinux for (CC Vincent); it appears to
build fine without it.  I made the dependency conditional on
architecture in d15972194aaef17fd1f7fd713d235c70794c9d4f, that way QEMU
should still work on aarch64.

(speaking of aarch64, Cuirass is slowly catching up now:
<https://ci.guix.gnu.org/eval/8?status=succeeded>).

Thanks for the heads-up,
Marius
