commit: PR 22802: Skip debug link processing if not requested by the user
I am going to check in the patch below to address the performance
regression in readelf (and objdump) when displaying the details of a
file containing a large amount of debug information.
The problem was that the function to find DWO debug links needs to
read in and parse all of the debug information, even if there are DWO
links to be found, and this was being done even when the user had not
requested that debug links be displayed or followed.
