[Boost-build] bug: default 32bit build on Win7/64bit

bjam toolset=msvc-10.0 on a Win7/64bit invokes the MS compiler to 
compile 32 bit code (sizeof(void*) == 4) and ml.exe ist called instead 
of ml64.exe.

Only if I add the address-model property I get the expected behaviour: 
bjam toolset=msvc-10.0 address-model=64
