Hi Amadeusz,

Yes, the arceb-elf-gcc depends on a few libraries include libc6,

         linux-vdso.so.1 (0x00007ffd4a1f7000)
         libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f4c4f36e000)
         /lib64/ld-linux-x86-64.so.2 (0x00007f4c4f554000)

and the below version is used in 0day-CI:

ii  libc6:amd64                        2.33-7 
  amd64        GNU C Library: Shared libraries

Best Regards,
Rong Chen
