While starting the emulator from the command line - $ emulator64-arm -avd GalaxyS2 - I got a similiar (and maybe/hopefully) related message:

emulator: ERROR: Could not load OpenGLES emulation library: lib64OpenglRender.so: cannot open shared object file: No such file or directory

I found this file lib64OpenglRender.so through locate. It's in the tools/lib-subdirectory of the android-sdk-linux-dir.

So I created /etc/ld.so.conf.d/android_stuff.conf (you could of course add the following line to another *.conf-file in that directory) and put one line in:

path_to_android-sdk-linux_directory/tools/lib

Then call the configuration-tool: ldconfig (just without any parameter) and (at least in my case) the error-message went away.
