Here are the link times for the example mentioned in PR2342 and my application for various binutils. The patch helped a lot, but it's not the only problem.
| 22.214.171.124.2.2 | 2.16.1 | 2.16.1 +PR2342 patch
slowld | 4m 17s | 4m 16s | 15s
myapp | 11s | 13m 03s | 1m 07s
So the patch definitely fixes the problem the 'slowld' example had, and addresses most of the problem with myapp.
I'll try and run with a profiler to see if I can figure out where all the time is being spent.
BTW: in order to apply http://sourceware.org/ml/binutils/2006-04/msg00329.html, I had to apply http://sourceware.org/cgi-bin/cvsweb.cgi/src/bfd/elflink.c.diff?r1=1.143&r2=1.144&cvsroot=src first.
