blcr-util binary package in Ubuntu Xenial arm64

 BLCR (Berkeley Lab Checkpoint/Restart) allows programs running on
 Linux to be "checkpointed" (written entirely to a file), and then
 later "restarted".
 .
 BLCR can checkpoint both single- and multithreaded (pthreads)
 programs linked with the NPTL implementation of pthreads. BLCR is
 also able to save and restore groups of related processes together
 with the pipes that connect them.
 .
 This package contains utilities needed to launch and restart
 unmodified processes with checkpointing support.
