Hello Matthias,

I would like to add a sub-chapter to our documentation describing what is
needed to build U-Boot on Suse. Cf.
https://u-boot.readthedocs.io/en/latest/build/gcc.html

Unfortunately I could not find all the packages that need to be installed
in the Suse Tumbleweed Docker image.

For 'make qemu_arm64_defconfig && make' I get an error

   aarch64-suse-linux-ld.bfd: cannot find -lgcc

For 'make tests' a lot more seems to be missing.

Do you have a list of required packages?

Best regards

Heinrich
