I have tried:
bjam -sTools=darwin

(because the default is supposed to build single AND multi)


bjam -sTools=darwin "-sBUILD=<threading>multi"

(based on a post I saw from David Abrahams)

In both cases I get debug and release, static and dynamic versions of
each library (4 total of each), but they are all named as if they are
single-threaded. I'll try "bjam threading=multi" on the command line.
