[meta-freescale] libepoxy build error for i.MX6-based boards

[Prabhu S]

libepoxy.bb recipe is incomplete.
http://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta/recipes-graphics/libepoxy/libepoxy_1.2.bb
libepoxy will also supports OpenGL, if can be configured in the OECONF,
since all platforms does not support OpenGL. there should be way for
configuring this.

pkgconfig wil provide -DLINUX flags and currently it is being provided by
egl.pc. but the libepoxy is using opengl causing this problem.

for i.MX6, recommended to enable EGL rather than OpenGL/GLX.

So the proper fix is adding configure options in libepoxy.bb to
disable/enable GLX. And another fix is to add -DLINUX in the OpenGL
pkgconfig

libepoxy_%.bbappend is a workaround for now.
