nm is standardized by POSIX.2, so any changes to default output should
be made with reference to the standard.

According to IEEE Std 1003.2-1992 section 5.21.2, ``If no symbolic
information is available for a valid input file, the nm utility shall
report that fact, but should not consider that an error condition.''
My reading of the rest of 5.21 is that the fact should be reported on
stderr.
