How do I lookup the C source file for a builtin function (sub-routine)
like symbol-file() does for emacs lisp?

I assume you want to do so interactively, then :
C-h f your-function-name RET
You will need to have emacs sources installed, obviously. If you did not
build emacs from source, you probably have to find a package that
provides them.

Looking at the source for describe-function and describe-function-1:
(find-lisp-object-file-name 'car (symbol-function 'car))
replace 'car with any symbol denoting a function
