ccollins476ad opened a new issue #236: Conflicting dependencies yields inconsistent dependency graph
URL: https://github.com/apache/mynewt-newt/issues/236
 
 
   ```
   syscfg.vals:
       FOO: 1
   
   syscfg.vals.BAR:
       FOO: 1
   ```
   
   These two `syscfg.vals` mappings are in conflict.  The first enables `FOO` unconditionally; the second only enables `FOO` if bar is set.  When newt encounters a conflict like this, it accepts the first override it sees and discards the others.  Since these overrides are not processed in a consistent order, the result varies from build to build.
   
   Newt should not allow such conflicting overrides.  Initially, we can make newt emit a warning when it encounters this.  Later, we can change it to an error.
