RE: Excessive link time with 2.16.1

["David M. Lee" <dmlee at Crossroads dot com>]

I tried binutils 2.17.50.0.2.  The link time was over 10 minutes.

I finally got it to run with the profiler.  Looks like the bulk of the
time is spent in qsort, called from bfd_elf_match_symbols_in_sections.

I've attached the output from gprof.

The Linux binutils 2.17.50.0.2 includes that patch.
