Description
When building with toolset=msvc address-model=64 in a 32-bit shell on Win64, the cross tools (32-bit targeting 64-bit) instead of the native 64-bit tools are used. The reason is the PROCESSOR_ARCHITECTURE env var pretending to be a 32-bit environment. However, on 64-bit Windows, the correct native value can be found in PROCESSOR_ARCHITEW6432.
The attached patch makes the logic to determine the tools to use respect that alternative variable.
