 CMAKE_OSX_ARCHITECTURES earlier.

 Oh, I got it now. If I use
 {{{
 cmake -DCMAKE_OSX_ARCHITECTURES="x86_64" ...
 }}}
 then I get
 {{{
 Fortran_FLAGS =  -m64 -std=legacy -arch x86_64 -fPIC -I<...>
 }}}
 in {{{misc/minicern/CMakeFiles/minicern.dir/flags.make}}} indeed. So is
 that a bug in CMake passing the wrong flags to Fortran compiler then? On
 one hand it's true that it doesn't make sense to pass more than one
 architecture to C compiler if Fortran compiler is not able to create fat
 binaries. But on the other it doesn't make any sense at all if CMake
 passes -arch to Fortran.
