* New toolchain version - 1.5.2
* Update gcc to 11.2.0
* Update binutils to 2.37
* Remove support to x86

x86 toolchain is not used by Mimiker since we don't support that
architecture - let's remove support for that toolchain and reduce
complexity and build time of tools.

- build toolchain in container
- bump Debian version
- add ability to build & run Mimiker in local environment

Example how to build local env:
- git clone [email protected]:cahirwpz/mimiker.git
- cd mimiker
- podman build -t mimiker .
- podman container run -it --rm --hostname mimiker -v /home/user/mimiker:/root/mimiker mimiker /bin/bash
after last command you are in bash shell inside container, you can
install your favourite set of packages or just build Mimiker. All
changes are synchronized between local directory /home/user/mimiker and
/root/mimiker inside container, so you can use your favourite editor and
distro.

podman is not required but it's recommended (in non-priv mode). It's
possible to still run podman as root or use docker for that purpose but
then you are on your own with permissions inside mimiker directory.

Note: building container is *SLOW* and IO *INTENSIVE* process.
