Excessive link time with 2.16.1

Interesting.

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.

       | 2.15.94.0.2.2 |  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.
