I think for 32/64 thing, the right approach is to improve the toolsets. Just 
add

feature address-mode : 32 64 : propagated ;

to builtin jam and lines like

flags gcc.compile OPTIONS <address-mode>64 : -the-right-switch ;

to gcc.jam and sun.jam. As soon as you get it working, send a patch and I'll 
include this in CVS.

As for linux/solaris.... I'd suggest, as the first step, putting this into 
your project-root.jam:

local a = [ modules.peek feature : <os>.attributes ] ;
modules.poke feature : <os>.attributes : $(a) symmetric ;

this will cause Boost.Build to always include the value of the "os" feature in 
build path. We probably need a cleaner way to accomplish this task but the 
main idea will remain the same.

HTH,
Volodya
