Something pertaining to missing the implementations of the standard
library functions...

Apparently not only is <linkflags>-m32 required, so is <linkflags>-lstdc++ :D

So now just for future reference to others who might be thinking of
doing the same, you can try the following user-config.jam entry for

  using gcc : : distcc : <cxxflags>-m32 <linkflags>-m32 <linkflags>-lstdc++ ;

Thanks for the thought-provoking ideas Volodya!
