Whether runtime registration is needed is not dependent on the OS but the file format. For ELF, COFF, Mach-O or XCOFF, we can always use the linker support. This is important for baremetal platforms such as RTOS and UEFI platforms where there is no OS but we still don't want to use runtime registration and rely on linker support instead.
