[meta-raspberrypi] gles2 on raspi3

[Trevor Woerner <twoerner@gmail.com>]

Hi,

I seem to have all the pieces in place, but can't get gles2 to work on the
raspberry pi. Specifically I'm using the raspberry pi 3, but the 32-bit armv7
build.

gles2 is provided by userland, and I've compiled up a couple gles2 programs.
Compiling succeeds without issue, but running is another case.

E.g.

	# es2_info
	Error: eglGetDisplay() failed

	# glmark2-es2
	Error: eglGetDisplay() failed with error: 0x3000
	Error: eglGetDisplay() failed with error: 0x3000
	Error: main: Could not initialize canvas

	# google-chrome --use-gl=egl
	[3487:3487:0415/133334:ERROR:gl_surface_egl.cc(605)] EGL display query failed with error EGL_SUCCESS
	[3487:3487:0415/133334:ERROR:gl_surface_egl.cc(612)] eglInitialize Default failed with error EGL_BAD_DISPLAY
	[3487:3487:0415/133334:ERROR:gl_initializer_x11.cc(142)] GLSurfaceEGL::InitializeOneOff failed.
	[3487:3487:0415/133334:ERROR:sandbox_linux.cc(343)] InitializeSandbox() called with multiple threads in process gpu-process. 
	[3487:3487:0415/133334:ERROR:gpu_child_thread.cc(348)] Exiting GPU process due to errors during initialization

Thoughts?

Does anyone have any of these (or something else?) working?

Thanks and best regards,
	Trevor
