If we take that argument seriously, then I'm inclined to adjust my
upthread patch for Makefile.global.in so that it removes the extra
inclusions of libpgport/libpgcommon everywhere, not only macOS.
The rationale would be that it's not worth worrying about ABI
stability details on any straggler platforms.

Hmm, we'd better fix that then. Or is it their bug? It looks to me like
clang's argument is -exported_symbols_list=/path/to/exports.list, so
it must be translating that to "-e".
