Oops... Must check my eyes or learn to look a little backwards... Just 
before
the previous there was :

case "${host}--x${with_newlib}" in
   mips*--xyes)
     hardwire_newlib=1;;
   nvptx*--xyes)
     hardwire_newlib=1;;
esac

Nowhere else besides in the 'libgfortran' subdir this was seen. Duplicates
in 'configure.ac' and 'configure'. Maybe fixing the '.ac' could be enough or
then both. I'm not any expert in the GNU configury system...  It seems that
the choices for Fortran are quite limited and 'powerpc' should be added too.
