Indeed, there's the problem. api_mask is 1. Looking at the build logs,
I see that the -DFEATURE_ES defines weren't being added to the command
to compile intel_screen.c (and other driver files) but were used in
the compilation of other mesa core files.

I removed --enabled-shared-dricore from my configure line (I didn't
even mention it earlier because I didn't think it was important) and
now -DFEATURE_ES1=1 -DFEATURE_ES2=1 are used to compile the intel
driver. So, looks like a regression due to the shared-dricore work.

Thanks,
Matt
