IOW, you've got several target operating system and would like V2 to 
distinguish between them? One approach would be to add, in your 
'project-root.jam', the following code:

import feature : feature set-default ;
import os ;

feature target-os : solaris linux : implicit symmetric ;

local os-name = [ os.name ] ; 
feature.set-default target-os : $(os-name:L) ;

This will add a feature which controls target os, and make V2 to add that 
feature to target path. The default value of the feature will be the same as 
the os you're running. One note: I don't know what's the value of 'os.name' 
on solaris, and can't test since bjam does not want to build on the only 
solaris installation I have nearby, so you might need to change "solaris" to 
something else.

Is the above approach OK for you?
