I just upgraded 
(git-2.31.1_1+credential_osxkeychain+diff_highlight+doc+pcre+perl5_28.darwin_20.x86_64.tbz2)
 and /opt/local/etc/gitconfig is also an empty file on my system:

~ % ls -l /opt/local/etc/gitconfig
-rw-r--r--  1 root  admin  0 15 mei 20:27 /opt/local/etc/gitconfig

~ % mkdir tmp
~ % tar -C tmp -xf 
/opt/local/var/macports/software/git/git-2.31.1_1+credential_osxkeychain+diff_highlight+doc+pcre+perl5_28.darwin_20.x86_64.tbz2
~ % ls -l tmp/opt/local/etc/gitconfig
-rw-r--r--  1 breun  staff  0 15 mei 20:27 tmp/opt/local/etc/gitconfig

After reinstalling the file is still empty on my system:

~ % sudo port uninstall git
~ % sudo port -k install git
(…)
% ls -l /opt/local/etc/gitconfig
~ -rw-r--r--  1 root  admin  0 15 mei 20:38 /opt/local/etc/gitconfig
