Updating Make World https://www.freebsd.org/doc/handbook/makeworld.html

[Matthew Midgett]

As a newer Freebsd user I was updating from src and I asked Allan Jude
a question on irc about a step and he recommeded that we do "pkg-static 
upgrade -f" between steps 10 and 11 on https://www.freebsd.org/doc/hand
book/makeworld.html I can verify that I did this on 10 machines and
there was no issues.##SELECTION_END##
