I have a ~/user_config.jam with something like this line (bits have been

using gcc : 5~pic : g++ : <cxxflags>"-fPIC" <linkflags>"-pie" ;

The command line syntax may be different, but you can invoke the command
line, I think, with:

b2 toolset=gcc-5~pic ...

So perhaps:

b2 cxxflags=fPIC linkflags=-pie ...

For all I know there might be a feature for position independent code
now, which would make the syntax more convenient.

Steven Watanabe will be along shortly with the correct answer, I suspect.
