Can't build using OSXFUSE's compatibility layer - #16

So, I think the right fix would be to add /usr/local/lib/pkg_config after the configured PKG_CONFIG_PATH only on Darwin. Since fuse.pc is there, everything should work after that. Do you agree? It's still guessing, but a way better shot at it. Could you test it and send a pull request?

I certainly cannot speak for any other platform (besides the Mac, I only have Debian/Ubuntu Linux to play around with, and these already mount ext4 filesystems by default), but I believe that using pkg-config (note the hyphen and not the underscore) is pretty much the standard way of retrieving compilation flags for all Unix-based operating systems these days.

It's true that macOS/Darwin lacks them by default, but that's one of the reasons for using something like Homebrew 😀 which will happily populate the filesystem with all those correctly-configured .pc files for pkg-config... and keep them up to date, too!
