If any of the .o files are up to date (ie: if they are younger
than their corresponding .c file) the rule won't be invoked, and
therefore you won't have the object appear in the file. If you have
something like:
%.o: %.c
echo $< >> srcs
$(CC) $< -o $@
Then srcs will be a list of the sources that got built. Assuming,
of course, that you remember to erase "srcs" after every build;
otherwise, it's just going to be a continuous log of every file built
in every invocation of make since srcs was created.
