[PATCH] Add --print-dirs option for ldconfig

[Roland McGrath]

Exactly what uses is this intended for?  

It shows all the directories listed in configuration files.  It
doesn't show all the directories that ldconfig searches.  That's
because the hwcap-named subdirectories don't get added until inside
the same loop that finds the individual libraries.  So if the intent
is to list all the directories where ldconfig might find libraries,
then it needs more work.


Thanks,
Roland
