Looks like it is not related to arm64, but to clang version. For previous versions it was only warning about absence of header for printf and exit, but now it is an error. I'll try to add a patch.

Yes, it changed from a warning to an error in Xcode 12. The reason for that was potential arm64 ABI issues.

In 7752f4c66c4b4a08725b2dcf75fb71c558f48053/macports-ports (master):

primegen: Fix implicit function declarations

Fix issues in code that are causing error in Xcode 12 and caused
warnings in previous versions. Namely include missing stdio.h, use int
as return type for main and use return instead of exit in main.

Closes: #61870
