mal: I tried `sfdk build -p` only now, and the prepare script fails quite early:
```
Executing(%prep): /bin/sh -e /var/tmp/rpm-tmp.6NT1my
...
Patch #1 (openssl-1.1.1-build.patch):

/home/mersdk/.mb2/wrappers/openssl/patch: Refusing to patch dirty work tree - commit or reset your changes first.
error: Bad exit status from /var/tmp/rpm-tmp.6NT1my (%prep)
