+Subject: [PATCH] meson: fix logic for generating .pc files with old glvnd
+
+We want to generate PC files for non-glvnd builds and for builds with
+old glvnd, but the current logic doesn't do that, it builds them
+unconditionally, and for GLES it builds the shared libraries, which is
+also not what we want. This does not generate .pc files for gles1 or
+gles2. Which it we weren't doing before either, making this not a
+regression but a return to status-quo.o
+
+Closes: https://gitlab.freedesktop.org/mesa/mesa/issues/1838
+Fixes: 93df862b6affb6b8507e40601212a58012bfa873
+       ("meson: re-add incorrect pkg-config files with GLVND for backward compatibility")
