Compiling a cross toolchain can be a bit complicated. The mingw-w64 wiki has documentation on how to compile the mingw cross toolchain. https://sourceforge.net/p/mingw-w64/wiki2/Cross%20Win32%20and%20Win64%20compiler/ If you want other thread models (other than win32), you can compile the winpthreads library (--enable-threads=posix) or copy release/mingw64/* (--enable-threads) from the mcfgthread repository to /path/to/install/x86_64-w64-mingw32/ after compiling crt.
