- PXC#480: xtrabackup-v2 SST fails with multiple log_bin directives in my.cnf
If any given variable the xtrabackup-v2 sst script looks for is specified
multiple times in cnf file then it tend to pick both of them causing
some of the follow-up command to fail.
Avoid this programatic mistake by honoring only the last variable assigned
setting as done by mysqld too.
