Stop using "-multiply_defined suppress" on macOS.

We started to use this linker switch in commit 9df308697 of
2004-07-13, which was in the OS X 10.3 era.  Apparently it's been a
no-op since around OS X 10.9.  Apple's most recent toolchain version
actively complains about it, so it's time to get rid of it.
