Subject: [PATCH] services: Add x86_64 QEMU target.
Date: Mon,  7 Nov 2022 02:09:45 +0200

Greetings,

I was trying to build an x86_64 binary on an aarch64 machine, and noticed that
`qemu-binfmt-service-type' was missing the x86_64 platform definition.

* gnu/services/virtualization.scm (%x86_64): Add variable.
(%qemu-platforms) Add it.
