I'm working on updating linux-libre to 5.10.

Using the attached patch, I tried building an ephemeral VM for x86_64:

------
$ guix environment guix -- ./pre-inst-env guix system vm 
doc/os-config-bare-bones.texi
[...]
building /gnu/store/678f40zf8dpp4w63j8419zad6d7bi32a-linux-modules.drv...

Indeed, the virtio_console module is missing. For linux-libre 5.9, it
shows up here within the kernel store item:

'lib/modules/5.9.14/kernel/drivers/char/virtio_console.ko.gz'

The 5.10 kernel configuration has "CONFIG_VIRTIO_CONSOLE=y", as before.

Any ideas? I'm trying to build now with "CONFIG_VIRTIO_CONSOLE=m",
although I don't really know why "CONFIG_VIRTIO_CONSOLE=y" was creating
a module file previously.
