Hello,I have download the gcc arm toolchain sources (gcc-arm-none-eabi-8-2018-q4-major-src.tar.bz2) and I would like to build that on a computer x64 that running Ubuntu but I want the compiler to run on a host machine with aarch64-linux as architecture (build = x64 , host =aarch64-linux). Could you give me instructions on what to change on scripts so I can achieve that?Thank you,Thanos
