Wouldn't it be simpler to reverse this condition and only add the
sources/dependencies here for Aura?

GYP documentation suggests adding all sources first, and then removing
platform-specific ones later on; because "the sources list contains a useful
global list of all sources on all platforms with consistent sorting on all
platforms".
