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).
