Right, I think implementing a new generator is called for.
Say, define a new type DTRACE_EXE and a generator creating such a type.
The generator would try converting all sources to OBJ, create
a target for that dtrace-produced-obj, and then try to construct EXE
from everything. You can try using examples/generator for a skeleton
of new generator and consult builtin.jam/generator.jam for how
generators work.
