Makefile: allow rootfs overlays to override symbolic links
Since commit 0db34529f48 we use rsync with the --keep-dirlinks option to prevent overlays from accidentally overwriding /{usr,bin,sbin,lib} links when BR2_ROOTFS_MERGED_USR option is enabled. Unfortunately this also prevents replacing a symlink by a directory on purpose (e.g. /var/log, to persist system logs). Steps to reproduce: - enable BR2_ROOTFS_MERGED_USR and BR2_PACKAGE_SKELETON_INIT_SYSV - mkdir some_path/rootfs-overlay/var/log - enable BR2_ROOTFS_OVERLAY="some_path/rootfs-overlay" - run 'make' - 'target/var/log' is still a symlink to '../tmp', not a directory The --keep-dirlinks option can be dropped, since we run sanity checks on overlays. Now the rsync invocation is identical to the SYSTEM_RSYNC logic we have in system/system.mk, so use that variable.
