Oky Is there way to dump what dejavu sans it found?

We are using new harfbuzz:

[   22s] [326/807] cumulate libharfbuzz0-1.4.6-1.1

And with the dejavu sans I get the feeling they are not present in the
buildroot at the moment, only liberation sans and google carlito fonts. I
will try to add them and see if it changes anything (results to be seen in
couple of hours).

Anyway I think the test should first font-config verify it got at least the
font it requiires.

Cheers
