Add support for using ld.gold on linux.

To use ld.gold configure with:
  -DCMAKE_EXE_LINKER_FLAGS:STRING="-Wl,-use-gold".
ld.gold links the viewer on my machine in 8 seconds, as
opposed to 19 seconds with ld.bfd. Moreover, it uses a
LOT less memory during linking (about 750 MB instead of
2.5 GB!). Thanks to Siana Gearz for pointing out that
ld.gold is so much faster.
