Are you using VariantDir() to put things in build/? If so, I believe
you are seeing expected behaviour here.

However, it's unclear what SCons is supposed to do if you define an
Alias with the same name as a target file. Sounds like the file takes
precedence over the alias. Would be nice if it printed a warning when
you do this.
