Wharfie

Create feature branch for ticket [#1]

enable SPI and I2C on Raspberry Pi by default

added rules for 64 bit support

Prepared for the use of fakechroot, which actually failed atm. as I found no way of using it w/o heavily influence the host installation. And doing that would make the whole effort of avoiding root access futil$
But, it cleaned up the make targets pretty much.

- moved wpa_supplicant, as this is only an example configuration and has to be adopted by the user

- added options to get system info and to clean intermediate files.
- fixed a small issue in the argument parser, so that you can pass a different filename instead of "Wharfile"
