Only support building a single board at a time

Browse Source 
As a follow up to c461e20df3 ("make: Remove version from build output
path"), only support building a single version of a single board by
default. The build directory can still be specified by passing `BUILD`.

Fixes running the `clean` target when `BUILD` is a custom value or
`BOARD` isn't set.

Fixes: b03c960b4f ("make: Reduce build output")
