[Bug 1493888] [NEW] FGLRX incompatible with gcc 5

SRU Request:

[Impact]

The fglrx driver is not compatible with gcc 5.x. This causes the kernel
module to crash on initialisation. As a result, users will boot into a
black screen, as X will fail (except on Intel+AMD hybrid systems, where
intel is used).

[Test Case]
1. Either install (or upgrade to) Ubuntu 15.10 and fglrx
2. Reboot
3. Check the display, and the output of the "dmesg | grep fglrx" command (to see the actual crash)

Expected results: the system should be able to start X correctly.

Actual results:
The kernel module fails and X doesn't start.

[Regression Potential]
Low. Forcing fglrx to use gcc 4.9 is only a temporary workaround, and will be replaced with the proper fix once AMD makes it available.


__________________________________________________________________________

With a R9 280 and FGLRX on ubuntu 15.10 the graphics lock up. I am able
to SSH into the machine. I booted the older kernel (4.1.0-3-generic) and
it works with FGLRX. After purging FGLRX and using xserver-xorg-video-
radeon I am able to get the graphics working, but even it has issues
with my display port (The DVI ports are working correctly).
