[Boost-build] how to use builtin features/default values

Hi,

how can I use builtin features like <architecture>, <address-model>?
If I use them as a requirement for a target alternative boost.build can 
not resolve the alternatives. If I do a bjam  --debug-building I see 
that <architecture>, <address-model> is not set (as opposed to <target-os>).
I assumed that those properties will be automaticaly set by the values 
of the current platform:

<architecture> -> X86_64
<address-model> -> 64

But it seams it's not! Maybe it's a bug?

help is appreciated,

Oliver
