How To Build 32-bit FLOPPINUX on a 64-bit Operating System

Thanks to the help of pappp [https://pappp.net/] I now have the updated instruction for 64-bit operating systems. It is little bit more complicated and I still recommend using VM or some old hardware. Follow my 32-bit tutorial [https://bits.p1x.in/floppinux-an-embedded-linux-on-a-single-floppy/] and just make changes listed below.
