Are projects likely to grab a common kconfig binary externally, rather
than build their own?  Where exactly is the benefit, here?

Except that conf_parse() uses PROJECT_NAME halfway through.
How do I handle that one?

Here's a patch with all the uses of PROJECT_NAME converted to
project_name, and with all the ones but the conf_parse() one
converted to an %s with project-name in the printf argument list. 

If you know how to fix up conf_parse(), the #define can be yanked from
lkc.h and replaced with a global variable...
