You have to do more than that.  multilib_defaults only controls what 
libraries we link against.  You also need to pass -mthumb by default to 
cc1 and perhaps also the assembler and linker.  Try using gcc -v -mthumb 
  and comparing the result against gcc -v, and then writing specs that 
mimic what -v -mthumb does.
