## Description of the issue
docker-compose build (in two separate projects) fails
## Context information (for bug reports)
Output of docker-compose version
```plain text
$ docker-compose version
docker-compose version 1.29.2, build 5becea4c
docker-py version: 5.0.0

Output of docker-compose config (Make sure to add the relevant -f and other flags)
```plain text
docker-compose config
services:
server:
build:
context: /home/leeh/code/stuart/gov-arch-modelling
command:
- java
- -Djava.awt.headless=true
- -jar
- /plantuml.jar
- -picoweb
ports:
- published: 8095
target: 8080
version: '3.9'
```
## Steps to reproduce the issue
1. Run any docker-compose build
2. Observe failure as denoted
### Observed result
Build fails with a python error, in my limited debugging capabilties, I have traced that to a fault with the iidfile being empty in class _CLIBuilder's build function. Line #1950 https://github.com/docker/compose/blob/master/compose/service.py#L1948-L1951
### Expected result
Build succeeds
### Stacktrace / full error message
```plain text
docker-compose build

## Additional information
Docker Compose from RPM (at 1.27, or .28 or something) or from the curl|bash install method
The error goes away if I disable buildkit explicitly (e.g export COMPOSE_DOCKER_CLI_BUILD=0) however my build depends upon the -mount option to share an SSH key socket with one of my builds, so I cannot build my actual project.
