[scummvm-devel] How properly exclude Ultima 4&6 from release build?

[Fiodar Stryzhniou.]

Hi! Ultima 4&6 incompatible with Symbian port. Symptoms: exe doesn't start. Debugger says it can't run exe. exe runs if these subengines excluded.
I opened pr for that some time ago but it was declined. How properly cut off these incompatible subengines for Symbian port? Release soon, respond please.
