Namhyung Kim 860df5833e tools lib traceevent: Make dependency files regeneratable ... Ingo reported that libtraceevent doesn't clean out dependency (.d) files and it can cause a build error when the libgcc package upgraded: comet:~/tip/tools/perf> make -j SUBDIR ../lib/traceevent/ make[1]: *** No rule to make target `/usr/lib/gcc/x86_64-redhat-linux/4.7.0/include/stddef.h', needed by `event-parse.o'. Stop. make: *** [../lib/traceevent//libtraceevent.a] Error 2 So this patch makes the .d files depends on the source and header files also, so that it can be re-generated as needed. NOTE: This code is copied from the GNU make manual page (4.14 Generating Prerequisites Automatically).
