    headers_check: don't warn about c++ guards · 92181d47

    A recent addition to the DRM tree for 4.7 added 'extern "C"' guards
    for c++ to all the DRM headers, and that now causes warnings
    in 'make headers_check':
    
    usr/include/drm/amdgpu_drm.h:38: userspace cannot reference function or variable defined in the kernel
    usr/include/drm/drm.h:63: userspace cannot reference function or variable defined in the kernel
    usr/include/drm/drm.h:699: userspace cannot reference function or variable defined in the kernel
    usr/include/drm/drm_fourcc.h:30: userspace cannot reference function or variable defined in the kernel
    usr/include/drm/drm_mode.h:33: userspace cannot reference function or variable defined in the kernel
    usr/include/drm/drm_sarea.h:38: userspace cannot reference function or variable defined in the kernel
    usr/include/drm/exynos_drm.h:21: userspace cannot reference function or variable defined in the kernel
    usr/include/drm/i810_drm.h:7: userspace cannot reference function or variable defined in the kernel
    
    This changes the headers_check.pl script to not warn about this.
    I'm listing the merge commit as introducing the problem, because
    there are several patches in this branch that each do this for
    one file.
