Although the user is free to choose where to put project-specific files, the
presentation 'Using Buildroot for real projects' [1] first described a
certain recommendation.
This patch briefly describes this recommendation in the form of a directory
structure overview, the details will be added in subsequent patches.
Since the section on BR2_EXTERNAL is logically connected to the directory
structure, this section is moved right after it.
