[CRIU] [PATCH] criu: add -fprofile-update=atomic for builds with gcov

[Andrei Vagin]

Sometimes we see errors like this:
criu/cr-restore.gcda:Merge mismatch for function 106

It proabably means that this gcda file was corrupted. According to the
gcc man page, the -fprofile-update=atomic should fix this problem.
