> Newt automatically creates a few macros on the command line when it builds a target:
> * {{ARCH_<arch-name>}}
> * {{ARCH_NAME="<arch-name>"}}
> * {{APP_<arch-name>}}
> * {{APP_NAME="<arch-name>"}}
> * {{BSP_<arch-name>}}
> * {{BSP_NAME="<arch-name>"}}
> There is a problem with the two APP defines.  A split image consists of two apps (the "loader" and the "app"), so there is not a single correct value to specify during compilation.
> There are two issues here:
> * Code cannot rely on consistent values for the APP defines when it is part of a split image
> * Newt performs unnecessary compiling and linking operations for repeat builds of split targets.  This is because the command-line invocation changes between builds, as the APP name is not consistent.
