No you don't, MinGW(-w64) targets windows directly (with MinGW statically linked in). I've built a Windows->Linux cross-compiler that depends solely on DLLs built-in to Windows (kernel32.dll, MSVCRT.dll, and user32.dll).

Granted that was hundreds of hours, some patches (only 8 lines though), and probably a bit of masochism.

I did of course need MSYS2 command line utilities like make and bison to run the GCC configuration/make scripts. Although we use the mingw32 version of make along with the cross-compiler which also has no other dependencies (it uses cmd.exe as a shell if you don't have a bash.exe in your PATH).
