The default variables and rules are compiled into the make binary, so
there is no file that you can edit to change them in the installed
package.

Changing the default rules locally would almost certainly be a Bad
Idea.  If you don't want the default rules, invoke make with the -R
option.  If you just want to alter them, then you should override them
in your Makefile(s). If you change the GNU make package that's
installed, then you've created an unexpected dependency on local
modification, and the make installed on the system can no longer be
simply upgraded with the OS as time passes.
