If I recall and understood correctly, mesa doesn't contain the Khronos group
.spec/.tm files, but the equivalent data in some XML format.

I hope I didn't imagine that, as not only would this solve the problem at
hand, but I think would also be a better solution as (i) my comedy python code
which parses those files could be replaced by using an XML parser, and (ii)
the spec would come from a versioned source.

Anyhow, I fully accept this is less than ideal as it stands, and I'll try to
come up with something better for the future, as time permits.
