Issue MESOS-3161: Document using the gold linker for faster development on linux.
The [gold linker|https://en.wikipedia.org/wiki/Gold_(linker)] seems to provide a decent speedup (about ~20%) on a parallel build. From a quick test: {noformat: title=timings for make check -j24 GTEST_FILTER="" w/ 24 hyperthreaded cores} gold: real	7m18.526s user	81m21.213s sys	5m17.224s default ld: real	9m7.908s user	85m13.466s sys	5m52.199s {noformat} On CentOS 5 w/ devtoolset-2: {noformat} sudo /usr/sbin/alternatives --altdir /opt/rh/devtoolset-2/root/etc/alternatives --admindir /opt/rh/devtoolset-2/root/var/lib/alternatives --set ld /opt/rh/devtoolset-2/root/usr/bin/ld.gold {noformat} On Ubuntu: {noformat} sudo update-alternatives --install /usr/bin/ld ld /usr/bin/gold 1 {noformat} Ideally we could this out on the website, with instructions for each OS.
