Subject: [PATCH] configure: setup for OE-core usage

Upstream-Status: Inappropriate

RPI-Distro repo clones original ffmpeg and applies patches to enable
raspiberry pi support.

Add global CFLAGS and LDFLAGS. So, that when
./configure runs test it's able to locate proper
headers and libs in a cross-compile environment.

Add new check to opengl. None of the above headers
exists and we also should be using GLESv2.

Update where compiler finds OMX_Core.h

Only check that sdl2 version greater than 3.0.0
