I'm hoping that once we'll be able to compile a simple program under gcc, 
someone interested in Boost.Build might want to contribute.

Oh... that would only require that target names do not clash with toolset and 
build variants. Okay with me.
But... Can we handle command line arguments? Won't they be unconditionally 
treated as target names by jam? 

So, is the following okay?
1. If command line mentions any toolset, we using the build request from 
command line verbatim, otherwise we add a "default" set of toolsets.
2. default-build is used when command line either specifies no build request, 
or specifies only toolsets.
default-build cannot specify toolsets (it seems unreasonable)
it is augmented with either the default set of toolsets or the toolsets given 
in the command line.
