When you add libgles-omap3 on the IMAGE_INSTALL, with the right flags Qt 5 is
compiled against it.
The problem is when you run "bitbake meta-toolchain-qt5", the resulting
toolchain doesn't have the libgles-omap3 libraries included.
If you look on the qtbase do_package log, you can see that:

NOTE: Couldn't find shared library provider for libGLESv2.so, used by files:
[...]

This is because for each library, Yocto will add the library name (coming from
the SONAME) to the .list/.ver files of the corresponding package.
Because for some reason those proprietary libraries don't have a SONAME, Yocto
fails to do so.

This patch is not 100% perfect, because files from others PACKAGES will produce
similar errors, for example:

DEBUG: calculating shlib requirements for libgles-omap3-es5
NOTE: Couldn't find shared library provider for libIMGegl.so, used by files:
[...]

But at least it permits other packages like qtbase to find the libgles-omap3
dependency, so that it will be included in the sysroot.
I made patches for oe-core (see [1] and [2]), if this is accepted it will be
possible to handle more gracefully with the ASSUME_SONAME variable.
