There was a version of Fontconfig that stopped recognizing “bold” as a
value for the “weight” property for a while. I run Debian Unstable, and
as I recall this did get fixed, but it looks like the previous version
was left in Stable for version 10.

As a workaround, try “weight=200” in your pattern.
