Yes. There is also no need to build the tools first. They are built as a 
part of the full build procedure as well. Not sure what you mean by 
manual creation of /usr/obj. You just need to create that one directory, 
and then the build process will create everything underneath.

No. /usr/obj.

In addition, the actual tools are placed in a directory that is specific 
to the version of the system, the target architecture, and possibly some 
other details I might have forgotten. But the reason for this is that 
you might be building for several different architectures on one 
machine, and you do not want those toolsets to overwrite each other.
