GNU make tries to rebuild any makefiles it uses. While in general it's a good idea (and it is used e.g. in autoconf-based builds), in our case it is not necessary, as all the makefiles are static. More to say, as we have a few "match anything" rules for subdirectories, Makefiles in these subdirs are also matching these rules, which leads to excessive (re)building while a particular makefile is needed. Protect such Makefiles with explicit (or pattern) rules, so make knows it should do nothing to rebuild those.
