I did not expect to need a mingw-runtime before the 2nd step (creating  
a --build=x86_64-suse-linux --host=mingw --target=mingw compiler) -  
see below.

You see me confused. I thought that a "--build=x86_64-suse-linux  
--host=x86_64-suse-linux" compiler is to run under Linux - what does  
is need a MinGW runtime so soon? - I am only trying to create the  
cross-compiler itself - I am not yet trying to create any MinGW  
binaries with it.
