Norbert Wesp 574607702b Add GBM_CFLAGS and define EGL_PLATFORM_GBM_MESA
Building an image with yocto for an 'am335x' processor will fail,
because 'gbm.h' can not be found and 'EGL_PLATFORM_GBM_MESA' is not defined.

So simply adding define of 'EGL_PLATFORM_GBM_MESA' in 'gstgldisplay_egl.c'
and adding 'GBM_CFLAGS' in 'gst-gl.m4' to get rid of this errors and complete
a full build process.

ERRORs were:
-----------
gst-plugins-base-1.14.1/gst-libs/gst/gl/gbm/gstglwindow_gbm_egl.h:24:10:
fatal error: gbm.h: No such file or directory

All aclocal .m4 files we need are put here and cat'd to acinclude.m4 in 
the source root.  Official ones (taken from the relevant devel packages) 
are named as-is, unofficial ones (or changed ones) get a gst-prefix.
