compile openvaf for Ubuntu and Apple

[fidel2030]

When compiling in Ubuntu this function gets called fn gen_msvcrt_importlib(sh: &Shell, arch: &str, target: &str, check: bool)
It appends target and calls command:
"clang-cl /c /Zl /GS- /clang:--target={target}-pc-windows-msvc /clang:-o{ucrt_obj} {ucrt_src}"

Is this for Windows compiling? How to change it to Ubuntu, on an Ubuntu computer, and to x86_64-apple-darwin for Apple?
