current USE_SSP=yes build failure

[rudolf <netbsd%eq.cz@localhost>]

Hi,

I have "USE_SSP=yes" in mk.conf and the build is failing with:

--- dependall-drivers ---
/usr/xsrc/external/mit/xorg-server/dist/hw/xfree86/drivers/modesetting/drmmode_display.c: 
In function 'drmmode_crtc_gamma_set':
/usr/xsrc/external/mit/xorg-server/dist/hw/xfree86/drivers/modesetting/drmmode_display.c:1768:1: 
error: stack protector not protecting local variables: variable length 
buffer [-Werror=stack-protector]
 1768 | drmmode_crtc_gamma_set(xf86CrtcPtr crtc, uint16_t * red, 
uint16_t * green,
      | ^~~~~~~~~~~~~~~~~~~~~~

Is this to be expected? Am I doing something wrong? The function itself 
is very simple.

Thanks,

r.
