This problem is actually occurring as part of the automated trunk 
regression testing, not a local build, so it is slightly more 
inconvenient to specifically exclude this library from the test suite.

However, I think there is a fairly simple fix to allow the build of 
Boost.Context to fail gracefully in the event that the architecture is 
unsupported.  Supplying a default 'fall back' alias for 
asm_context_sources to be used when no other alias matches should keep 
the Boost.Build file from throwing an hard error.  Please see the 
attached patch.
