Some bullshit I needed for multiarch gdb without compiling from source using docker.
Probably doesn't work on windows because of network_mode: "host" (which is a feature i hate gayndows) but... shouldn´t you be using wsl anyways? And if so you already have multiarch gdb with launchpad lol. This is for those who don't (opensuse) and don´t want to (or failed to) build from source.
Build the docker container with docker build -t gdb-multiarch -f gdb-multiarch.Dockerfile .
Try to make with libdragon make D=1
