Instructions how to build dfu-util on OS X

For future versions, I think dfu-util should be able to detect whether it is talking to a dfuse device, and then switch automatically to dfuse communication mode and expect a dfuse file (unless an advanced user wants to download a raw binary file to it). So –dfuse default will not be needed, and –dfuse address might be renamed to avoid confusion.

This has now happened, and I have updated garden.seeedstudio.com/index.php?title=Dfu-util with the new syntax. As you can see there, the new code uses libusb 1.0. It would be nice if someone on Mac OS X can confirm that the build instructions are correct.

BTW, this code will soon go into the official dfu-tool version 0.5, so that it will be available through normal distributions.
