[boost] Boost 1.54 build problem: --without-context not honoured?

Hi,

I'm digging into a build problem and noticed that even though I specify 
"./bjam --without-context", Boost.Context is still built!  The bjam 
configuration output states that Context is not to be built:

Component configuration:

    - atomic                   : building
    - chrono                   : building
    - context                  : not building
    - coroutine                : building
    - date_time                : building
    - exception                : building

But it is built nonetheless.  This causes a build failure for architectures 
which are not supported; see build log [1].  Compare that to the build for 
1.53 [2] which works fine.

I've diffed the libs/context directory between 1.53 and 1.54 and nothing jumps 
out at me as the cause.   Has anyone noticed and fixed this already?

Thanks,
-Steve
