No, it is not really hiding. This commit adds the conflicting files, which are not needed anymore.

That can be another way to fix the problem. But the issue is not only with mesa-dri, I was seeing conflicts with other recipes too as seen below.

So I think at this point in the 1.4 release, the least disturbing solution will be to revert the commit adding .pc files to emgd recipe.
