You can not override the spec file, but you can still replace

   %define build_ada 1

in the spec file by something like

   %define build_ada %{?my_build_ada}%{?!my_build_ada:1}

(untested), which would mean that "1" is taken when you don't
define "my_build_ada", or the value of %{my_build_ada} when you
define it on the command line with

   --define 'my_build_ada 0'

As said, it's untested, as I'm not sure about whether the
evaluation of %{?!my_build_ada:...} actually works when the
value is zero.
