collecting words / incremental compilation.

suppose we're building a kernel. that kernel is represented by a
single module. when instantiating that module, we get access to the
exported words. these are linked to structures that might not be
provided explicitly.

all dependencies are handled, and the required target code can be
computed by flattening the call graph given the entry points.

this means the problem of getting a linked kernel with limited entry
points is separate from building a library of macros accessible in
other programs. maybe time to start working on incremental
