One of the assumptions in the NetBSD build system is that you 
have the entire source tree and intend to build it all, or that 
you will manually build some subsets in an appropriate order to 
satisfy dependencies.  For example, if you don't build it all, 
then you will at least need to build (some) includes and (some) 
libraries before building applications.

Another important assumption is that the build is run on a host 
with a unix-like file system (hierarchical directory tree, with 
"/" as a directory separator, with atomic rename, with long file 
names), with several unix-like tools (cp, ln, mv, mkdir, echo, 
etc.), with a compiler and host include files and host libraries 
that allows "build.sh tools" to work.  If you have a host that is 
mostly unix-like, but where build.sh tools fails, then I think 
NetBSD will be interested in fixing that.
