The definition of "system_has_drm_kms" is orthogonal to EGL.
Explaining one with the other makes things more confusing, than they
already are.
Please try to avoid that.

outside "system_has_drm_kms"
 - Windows (msvc, mingw), MacOS, Cygwin, Haiku,  GNU Hurd
within "system_has_drm_kms"
 - Linux, BSD, NixOS and Solaris

"no" egl
 - Windows (msvc, mingw) and MacOS
has egl
 - everything else
