Here is strace log for this case:

$ strace -fF -e trace=readlink,access rsync -a src/ dst/
Process 1328 attached
[pid  1328] --- SIGSTOP (Stopped (signal)) @ 0 (0) ---
[pid  1327] access(".", R_OK)           = 0
[pid  1327] readlink("broken-link", "missing", 4095) = 7
[pid  1327] access("broken-link", R_OK) = -1 ENOENT (No such file or directory)
Process 1329 attached
[pid  1329] --- SIGSTOP (Stopped (signal)) @ 0 (0) ---
