This isn't really possible because this information
is determined on a per-target basis. e.g. it's
perfectly fine to build both static and shared
libraries at the same time.

It's called --debug-building, which outputs
the properties used to build each target.
You may not like the volume of output, though.

  This isn't exactly our intention.
Properties in Boost.Build can come
from many different sources, and
we have rules to specify how they're
merged. It sounds like the specific
problem that you're complaining about
here is that target/project properties
override the command line. This behavior
is absolutely necessary in some cases.
