I thought about this: why can't we call openlog/syslog to make sure the
error makes it to the logs? Since the program is single-threaded and is
going to abort(), we are assured we will not disturb it, won't we?

Something like this:

void
_rtld_noload_stub(void) {
        openlog(progname(), LOG_DAEMON, LOG_CONS|LOG_PERROR);
        syslog(LOG_CRIT, "Symbol call for unloadable object");
        abort();
}
