It's a problem that catches many young players with find(1). One has
to remember from reading the man-page that all directives have an
implicit AND operator on it; and that includes the "-print" directive.
So to get what you want, you have to introduce brackets:
find /usr/src \( -name Makefile -or -name '*.mk' \) -print
Cheers.
