Build on Ubuntu 18.04 x86_64

I listed my test environment at 2022.Feb.19 (I'm not saying it cannot compile in others, but at least my environment works)

1. Intel I7-7700k
2. Ubuntu 18.04

git clone https://github.com/cpuwolf/myos-ia32.git

cd myos-ia32

git checkout alive

make vfd

expect fdImage.vfd file is created, and file size is floppy disk size 1.44MB

fdImage.vfd will be used by VirtualBox later on
