qemu user static for aarch64 and arm

• qemu needs to be emerged with USE="static-user".

wget

You need to download the stage 3 tarball you want to use, and put it in build-binary-assets/stage3. Edit config/config.py and update the path to the stage3 version you're using.

Pick a target by running export PROJECT=<projectname> default is GenPi64OpenRC.

If you want to set where the build should happen, run export PROJECT_DIR=</path/to/build/location> default is $PWD/build/$PROJECT.

Then run sh build.sh. Wait (a long time). At the end, you should have your output in $PROJECT_DIR.
Packages are in $PROJECT_DIR/packages, the image file is in $PROJECT_DIR/. There's also a stage4 generated, in the same location.

There's a convenience script source set-env.sh that will export the useful variables for you, mostly used by the project maintainers to run a build of our own.

If you are building an arm target via qemu, you probably want a distcc server running with crossdev gcc as it takes DAYS to build.

You can configure the project via config/pyconfig/*.py, each PROJECT has its own config file.
The default is GenPi64OpenRC. You can override the default by setting PROJECT in the environment. The steps to execute are governed by the .json files in the project root.

Compiling python often hangs running compileall.py. It's safe to kill the hung tasks.

If . env.sh you can manually run a parser and better assess its output. You can also ./chroot.sh and manually tweak things inside the prefix.

If you're getting either of these errors, you probably need to install qemu user static and configure it for the target arch.
