math/blas on netbsd-7

[Stephen Borrill <netbsd%precedence.co.uk@localhost>]

On a bootstrapped netbsd-7 installation I cannot build math/blas which is 
needed for net/nmap

-- Check for working Fortran compiler: 
/usr/pkgsrc/math/blas/work/.cwrapper/bin/gfortran - broken
CMake Error at /usr/pkg/share/cmake-3.19/Modules/CMakeTestFortranCompiler.cmake:51 
(message):
  The Fortran compiler

    "/usr/pkgsrc/math/blas/work/.cwrapper/bin/gfortran"

  is not able to compile a simple test program.

  It fails with the following output:
