It's a distro setup difference I think, on Debian
x86_64-w64-mingw32-gcc is a symlink to x86_64-w64-mingw32-gcc-win32:

$ ls -l /usr/bin/x86_64-w64-mingw32-gcc-win32
-rwxr-xr-x 2 root root 1160320 Nov 27 05:57
/usr/bin/x86_64-w64-mingw32-gcc-win32
$ ls -l /usr/bin/x86_64-w64-mingw32-gcc
lrwxrwxrwx 1 root root 40 Sep 27 18:41 /usr/bin/x86_64-w64-mingw32-gcc
-> /etc/alternatives/x86_64-w64-mingw32-gcc
$ ls -l /etc/alternatives/x86_64-w64-mingw32-gcc
lrwxrwxrwx 1 root root 37 Sep 27 18:44
/etc/alternatives/x86_64-w64-mingw32-gcc ->
/usr/bin/x86_64-w64-mingw32-gcc-win32
