project.py - changed (unlogical?) behaviour

[ohagendorf]

Some commits before it was possible to call:

project.py -S

to get the supported matrix of MCUs and IDEs.
Now I get:

usage: project.py [-h] -m MCU -i IDE [-c] [-p PROGRAM] [-n PROGRAM] [-b] [-L]
                  [-S] [-E] [--source SOURCE_DIR] [-D MACROS]
project.py: error: argument -m/--mcu is required

and have to call e.g.

project.py -S -m ARCH_MAX -i uvision5

to get this tables.
The same error is generated with :

project.py -L

build.py and make.py with option -S are working as before.

I think it was introduced in PR #2010
Maybe @theotherjimmy can help.

Yep. On it.
