Kir Kolyshkin ab90777ca1 Makefiles: protect from % rules, don't rebuild
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.

CRIU (Checkpoint and Restore in Userspace)

An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space.

The project home is at http://criu.org.
