Auxtrace support may need DSOs for decoding (for example Arm
Coresight). If one of these is missing it would make sense to
warn once for each one that's missing, but not flood the output
with every address as there could be thousands of lookups.

This flag will allow tracking whether a warning was shown for
each DSO.
