Use same dependencies as docker container in alphabetic order

[sharkwouter]

There were a couple of dependencies missing and a couple which were not needed in both the readme and the dependency install script. Here is a list:

• Cmake and Doxygen were not in the list at the top.
• The list at the top was almost alphabetically ordered, but not quite.
• The command for installing the dependencies on Ubuntu had build-essential and libsdl-dev in it, which are not required.

Now I do really wonder if Doxygen is used when building the toolchain. The toolchain script does check if it is there, but that was the case for SDL as well, which wasn't needed either.

• doxygen is used by some libraries for generating documentation (e.g. opentri)
• build_essential is a meta package that provides gcc, g++ and make.
  These are explicitly included already, but it should be included if the debian folks ever decide to rename packages or something.

[sharkwouter]

Ah, that explains the doxygen mystery. I did find it is being used by 2 packages when I build the toolchain again.

Since we were already telling people explicitly to install gcc, g++ and make, we may as well leave out build-essential, in case more which we don't need is added to it in future versions.

I would like to merge this after adaption in/from #118.

[sharkwouter]

The following were added after making this merge request and will be removed if this is merged:

• xz-utils
• bzip2
• gzip

I'm not sure if these are really necessary. Especially xz-utils seems odd. gzip and bzip2 are part installed by default on most systems, but setting tar instead may make more sense..

[sharkwouter]

Okay, I see now, this was added in commit 5fc6ae5. Will add them back.

[carstene1ns]

gmp, mpfr and mpc should be removed, they are not needed and will be built.
The compression formats should be listed explicitly, as we cannot guarantee archives get extracted after switching to them.

[sharkwouter]

I've added them back in and included tar. I'm currently testing to see if the toolchain builds with the dependencies you mentioned removed in from the Dockerfile, will update when it's done building.

[sharkwouter]

@carstene1ns you were right, no issues with those dependencies not installed.

[sharkwouter]

I've now added pkg-config as well.

[carstene1ns]

What about pacman libs?

[sharkwouter]

Okay, I've added the pacman dependencies to the README and the debian/ubuntu prepare script.
