Subject: [PATCH] core: enable firmware build without SDL2 installed

SConstruct includes SConscript.unix even for the firmware builds,
which resuls in error if SDL2 is not installed.
This commit workarounds the issue.

Is there a better way how to NOT include SConscript.unix via
SConstruct for firmware only builds?
