I see the problem with undefined symbols. This is something that should not be happening. I think you are right and extraction from archive somehow damaged the file.
After doing some tests, I think the problem is in the x86 Build, I installed "AROS One + ABIv11 Host Linux", and the GCC worked fine, and the source compilation also worked correctly, see screenshot.
Then I used the "same Development folder" on x86 and got the usual error
