@prarit I was about to merge this, but just noticed:
```
redhat/self-test/data/create-data.sh:makefile_vars=$(unset SINGLE_TARBALL;
make
dist-dump-variables | grep "=" | cut -d"=" -f1)
```
There is still SINGLE_TARBALL present in create-data.sh script, remove it
there as
well?
Oops. Fixed and re-tested.
