Hi Guys,

  I have recently seen several bug reports about readelf and objdump
  unexpectedly slowing down.  The problem turns out to be due to
  attempts to access debuginfod servers which are either not there or
  just slow to respond.  So to help alleviate this problem I am applying
  the patch below which adds a new command line option:
  
    --dwarf=do-not-use-debuginfod       (objdump)
    --debug-dump=do-not-use-debuginfod  (readelf)

  Along with the equivalent =use-debuginfod option and short versions of
  both.  The default behaviour is not changed, so the patch should not
  impact any scripts that are currently relying upon the debuginfod
  support.

Cheers
  Nick
