Kir Kolyshkin 964a501b16 criu/pie/Makefile: disable FORTIFY_SOURCE 
This is highly controversial, but fixes the following compilation
problem with Alpine Linux (i.e. musl libc) caused by the previous
commit (""):

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.
