all: remove need for `-fcommon`
Use `extern` where appropriate so that we can remove `-fcommon` on macOS and others. On macOS, `-fcommon` generates a number of linker warnings. I've tested building on macOS, Linux, FreeBSD, NetBSD, OpenBSD and illumos. I am not in a position to test on AIX or other more esoteric platforms, however.
