I suggest that you install gfortran system package, then Sage won't
need to try to build gfortran.
the package is called gcc-gfortran; you'll also need gcc-g++

here is a complete list to install, from
https://doc.sagemath.org/html/en/installation/source.html#linux-recommended-installation

$ sudo yum install binutils xz gcc gcc-c++ gcc-gfortran make m4 perl \
tar git patch perl-ExtUtils-MakeMaker openssl openssl-devel zlib-devel \
bzip2 bzip2-devel xz-devel gmp gmp-devel libcurl-devel curl yasm \
pkg-config ntl-devel mpfr-devel libmpc-devel libsymmetrica-devel \
eclib-devel gmp-ecm-devel lrcalc-devel isl-devel givaro-devel \
pari-devel pari-elldata pari-seadata pari-galdata pari-galpol \
m4ri-devel m4rie-devel L-function-devel

(more precisely, this list is for Fedora LInux, but it should be the same...)

after you're done installing these, in Sage's source directory, do

make distclean
./configure && make
