I think I'm confused.  There is no `BUILD' variable in the top-level
Makefile.  There is a `_BUILD', but that's specifically meant for internal
use by the `build' target.  So, what's up with the variable in
src/etc/Makefile?  Why isn't it documented at the top of the file, since
it's apparently meant to be used by end users?
