In my testing here on my Kubuntu 18.04 I've found the glGetProcAddressARB and getGetProcAddress functions were returning non NULL values for invalid function names. This looks like a driver bug to me, one that has potentially for affect far more than just the glGetTextureHandle usage. dlsym works reliably and has always has been there as a fallback so I've simply removed the getGetProcAddressARB code for linux:

I haven't tested any other OS's yet so would appreciate others testing out once of these three branches.
