It does not make any statement as to whether the symbols would be found for any other architecture nor whether the software supports or does not support x86_64. It might mean you forgot to specify the name of the library in which the symbols are found, or it could indicate a libc++/libstdc++ incompatibility. Or it could mean there is an architecture mismatch between the program and the library it's using, but since Macs have been x86_64 for many years that's not the first place I'd look.

I tried building another today that is bundled with oink-stack (https://github.com/dsw/oink-stack). This one was updated in june and gets to the last build phase with these errors:

It's good to fix warnings, but make sure you remove -Werror from the
build commands in the final version of the port.
