[Boost-build] [Mac XCode 3.1.1][boost_1_37_0] use MaxOSX10.4u.sdk

How do I specify that the osx 10.4 universal sdk is used when building 
boost_1_37_0 on Max OSX 10.5.5 and XCode 3.1.1.

Using:

bjam --toolset=darwin architecture=combined link=static debug release stage

uses the 10.5 sdk, which causes problems when our app links with 
boost::filesystem.

Thanks, Jeff
