+In 100_copy_as_is.sh error out if symlinking VAR_DIR SHARE_DIR fails (#3356) :
+In build/GNU/Linux/100_copy_as_is.sh 
+error out if symlinking VAR_DIR and/or SHARE_DIR fails 
+because with non-default VAR_DIR and/or SHARE_DIR 
+(e.g. when running from checkout) 
+it is mandatory that in the ReaR recovery system 
+all ReaR files are accessible via the default 
+/var/lib/rear and /usr/share/rear directories, 
+see https://github.com/rear/rear/pull/3356 
+So old systems with 'ln' from coreutils < 8.16 
+that does not support the '-r/--relative' option 
+are no longer supported because the 
+relative symlink is needed for portable mode, 
+see https://github.com/rear/rear/pull/3206
