Subject: bug#48393: Can't build installer on aarch64 / v86d fails to build on aarch64

I tried building the installer on my aarch64 computer, but it fails to
build v86d, as shown below.

This package v86d is used in the installer's uvesafb-shepherd-service
service, which is supposed to not be used on aarch64 (the 'start' action
of the service limits use to Intel-compatible systems).
