[Buildroot] [PATCH v2 1/1] package/sdl3: fix X11 dependencies

[Bernd Kuhls]

Add handling for optional X11 dependencies to fix configure errors.

Please note that SDL3 only checks for these dependencies when X11
support is enabled so we do not need to add =OFF options to the else-
clause -DSDL_X11=OFF:

Which configure errors? Does this needs to be backported?

Thanks!
