How do I make Git ignore file mode (chmod) changes?

I have a project in which I have to change the mode of files with chmod to 777 while developing, but which should not change in the main repo. Git picks up on chmod -R 777 . and marks all files as changed. Is there a way to make Git ignore mode changes that have been made to files?

git config core.fileMode false // git -c core.fileMode=false diff
