You need newer libelf.

This should result in a configure error, not an error at a later stage; it 
should disable LTO if libelf is too old and LTO is not explicitily 
requested, or give an error at configure time if LTO is explicitly 
requested but libelf is too old.

needs configure magician...
Comment 4 Steven Bosscher 2009-09-11 17:30:05 UTC 
...but bug is real.
Comment 5 Diego Novillo 2009-09-28 16:24:25 UTC 
Should be fixed now.  We now test for libelf features during configuration.  Please reopen if it still fails.
