I am pretty sure that the "Oh oh" error and the entry from Xorg.log are 
not related. I have the same error on my CentOS 6 but it still works 
perfectly fine.

That's my log without the symlink you made:

[    40.405] (II) fglrx(0): swlDriScreenInit for fglrx driver

And that's the log with the symlink:

On my system the end behavior is exactly the same, I for one do not 
perceive any difference at all. It could be, of course, that I am not 
using any of the functions potentially brought in by the fglrx_dri library

The "Oh oh..." message is normally a sign that your X installation 
misses some packages. I've seen it too a long time back ( more or less 2 
years ago ) but I do not remember exactly if I solved that replacing gdm 
with kdm in /etc/sysconfig/desktop ( which is the most probable thing I 
did ) or  the opposite, replacing kdm with gdm.  I do not yet use EL7 
anywhere so my ability to perform tests in this environment is limited. 
Try adding
         DISPLAYMANAGER = KDE
in  /etc/sysconfig/desktop. If you do more digging and find out how to 
make Gnome work and the changes require modifying the fglrx packages, 
let me know and if possible I will do those modifications.

That's an issue I know about. It was reported as 
https://elrepo.org/bugs/view.php?id=651 and 
https://elrepo.org/bugs/view.php?id=701 . I will investigate that as 
well but I am afraid it's due to a change that was introduced by EL 7.3 
and which, at least for now, I cannot solve. Some time ago a similar 
problem was solved by upgrading the drivers. Unfortunately I cannot 
figure out how to do a polite repackaging of the recent drivers shipped 
by ATI ( AMD ). In their current incarnation, AMD provides the 16.50 
drivers as a compressed tar which, upon extraction, gives a bunch of rpm 
packages and a bash script that in theory is supposed to install those 
packages plus some needed dependencies, taken from EPEL. Unpackaging  
those rpm packages and than repackaging is something I'd rather avoid 
doing. But as I said, I need to investigate further, due to lack of time 
I just skimmed over.
