In your original config.log, it looked like sage was picking up its own 
fortran:

configure:11991: gfortran has already been installed by SageMath
configure:39396: result: gfortran-9.2.0:                             
 already installed as an SPKG

The current version of gfortran from homebrew is 10.2.0 version 3

GNU Fortran (Homebrew GCC 10.2.0_3) 10.2.0
Copyright (C) 2020 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

./configure should be picking up homebrew's gfortran (installed with gcc), 
and it seems from your config.log file that you do have homebrew and 
therefore you should have the most recent gfortran.
Do you have the newest config.log file from after running make distclean? 
You may also want to try running

brew doctor

to see if there is something wrong with your homebrew.
