autodoc - autodoc: Dramatically simplify installation process (Thanks

Log Message:
-----------
Dramatically simplify installation process (Thanks Simon Bertrang).

Complex installation checks have never been required so drop it and replace with simple
make functionality.

Targetting to a different installation prefix is done by setting the PREFIX variable:

make PREFIX=/some/new/home install
