added all the ps and other ppc extensions, need to decide on getopt for windows stuff and resolve default architecture

[v1X3Q0]

Adding the other powerpc extensions, unfortunately unix to windows differences require some external libraries.

• Need to decide if its ok to either submodule https://github.com/v1X3Q0/getopt-for-windows.git or if we should not include windows support.
• Default to ppc_ps for the architecture right now, need to fix it so it defaults to ppc and correctly allows selection of each architecture arbitrarily.
• To have each architecture properly selected, may require adding platforms for each.

Just to put it here, I've asked the author (on slack) to remove the getopt dependency, so test_asm/test_disasm won't support Windows for now.

I'm mariomain, windows stuff has been removed. will still look into the other 2 bullets in a bit.
