Perhaps it close #214549.

Logrotate doesn't allow dislocate olddir on a separate disk device
because it use `rename' syscall to do rotation. However, when logrotate
configured with `copytruncate' option, it use other procedure for file
rotation by using copy and `ftrunc' source file.
So we should check this situation on configure stage.
