[Disclaimer: This is merely my presumption. Although I occasionally
cross-compile other projects from Linux to Windows, I haven't tried
cross-compiling GCC itself from Linux at all.]

It should be easy to build a native compiler without having a cross
compiler first, as those pre-built CRT objects and libraries are already
everywhere and can be copied into the build system directly, so
configuring GCC with `--{host,target}=x86_64-w64-mingw32` for example
should be enough for creating a native compiler.

It is a cross binutils that is a must-have.
