[meta-freescale] [meta-fsl-arm][PATCH] gpu-viv-bin-mx6q.inc: fix libEGL and libGLESv2 installation

[Philip Craig]

Previously, we were only packaging libEGL.so and libGLESv2.so.  This
worked at runtime because ldconfig installed symlinks for the soname
of these libraries (libEGL.so.1 and libGLESv2.so.2).

However, there are situations where we need the soname version of
these libraries at build time.  Specifically, if these libraries are
indirectly referenced by another library, then the linker looks them
up using the soname.

This patch changes the installation of these libraries to the normal
way of installing.  That is, we install them as the soname, and create
symlinks for libEGL.so and libGLESv2.so.2.  This also matches the way
that these libraries are provided in the source.

The one catch with that is libEGL.so also tries to load libGLESv2.so
directly at runtime, rather than using the soname, so we need to
install the libGLESv2.so symlink to the rootfs also, and we need to
disable a QA error to allow this.

libGL and libGLESv1 are fixed in a similar manner, but I haven't
tested them.

This fixes the following errors when building qtgstreamer:
