As I "predicted" from the beginning adding require_egl_drm() is a hack
which will inspire even more hacks.

For example 98cebc913cd7ad07ce9699b5f63d72fe3969c851 and now this one.
Please _drop_ these all together.

I realise what you're trying to be extra careful on behalf of the
user, but this is not the way to do it. Let's drop the "interesting"
enable-gbm auto-detection enabling it by default or toggling it on
supported platforms - !cygwin/windows and add the drm egl-platform if
gbm is enabled. This way your worries will be resolved, plus things
will be shorter and easier to untangle :-)
