The amdgpu plugin's local amdgpu_drm.h defines struct drm_color_ctm_3x4 guarded by #ifndef HAVE_DRM_COLOR_CTM_3X4, but HAVE_DRM_COLOR_CTM_3X4 was never defined by the build system. On systems where libdrm headers already provide this struct (e.g. Alpine with libdrm 2.4.131), clang rejects the redefinition as a hard error, while gcc silently accepts identical struct redefinitions as an extension. Add a feature test that checks whether struct drm_color_ctm_3x4 is available in the system drm_mode.h and pass -DHAVE_DRM_COLOR_CTM_3X4 when it is, so the local fallback definition is skipped.
