- Add a "host" attribute to the project's <include> and <define> tags to make it possible to define global includes/defines for host components
- Define TARGET_arm/TARGET_i386 in the ReactOS-arm.rbuild/ReactOS-i386.rbuild files for the host tools to make it possible for them to know about the target to build
- Make use of this define in winebuild to fix the issue of r36927 properly
- Define global includes for host tools to simplify all host tool/library rbuild files
- Remove dead rbuild code

- Remove the include/reactos/config.h file, none of its defines are still used
- Fix components accidentally using that file
