With just 128 kB, I think you'd want to only implement a SILK encoder or
a CELT encoder, with none of the optional functions (e.g. there's
sometimes more than one variant of a function, or analysis functions
that aren't absolutely necessary). For example, on X86 I think you can
implement a CELT encoder in about 40-50 kB. I'm not sure about SILK.
