Dear Maintainer,

Most of my machines run on debian testing with docker installed form the debian 
repository. For the longest time I could build docker containers with buildkit 
enabled. But at some point it stopped working. At first I thought that would be 
a temporary thing with some packages updating. These things happen from time to 
time on debian testing, and usually they resolve after a couple of days or 
sometimes weeks. But this problem with buildx has now existed for at least two 
months.

Simple containers that don't require features from buildx still build.

I didn't really find useful information on how to resolve by searching the 
internet. 

To reproduce, on an up to date debian trixie installation execute the following:
DOCKER_BUILDKIT=1 docker build --output some_files
I get the following error:

ERROR: BuildKit is enabled but the buildx component is missing or broken.
       Install the buildx component to build images with BuildKit:
       https://docs.docker.com/go/buildx/

Since I installed docker from the repository I would prefer not having to 
install buildx manually.
