[Boost-build] Try to intelligently select between different pre-built libraries.

Hello all,

In a (much) earlier message to this list I asked how to specify 
pre-built libraries that needed to be linked with one of my projects. 
The advice I was given was to use something like what follows;

lib comctl32 : : <name>comctl32.lib ;
lib user32 : : <name>user32.lib ;

That worked perfectly but now I need to achieve something more 
complicated. I have built the OpenSSL libraries with a number of 
different compiler switches and would like to have BBv2 select the 
correct library depending on, say, the build variant.

Ideally I would like to make selections based on more options. Off hand 
I can think of multi-threading and runtime-link being important. 
Different toolsets would also be useful, as would targeting 
address-model=64 because I am trying to make my project as portable as 
possible. As you can perhaps guess my project uses ASIO and I'd like to 
support SSL.

I've made a couple of attempts but failed spectacularly so I would be 
very grateful for any tips.
Kind regards, Eoin.
