In download section for cross-compilers I see 2 options that seem viable for AArch64 cross-compiler under x86-64 Linux:
gcc-arm-9.2-2019.12-x86_64-aarch64-none-elf.tar.xz
and
gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu.tar.xz
The problem is that I fail to understand the difference - can you, please, explain (or point me to explanation)?
