Merge notes on Linuxisms from a wiki page to the FreeBSD porters handbook

Description of task
The FreeBSD ports collection consists of a variety of ported software that oftentimes was not originally written for FreeBSD. As such, porters who want to make this software available for FreeBSD users, need to make special arrangements in order to run the software from other Unix-like operating systems such as GNU/Linux. Instructions and helpful advice on how to do that is available on the following wiki page: http://wiki.freebsd.org/AvoidingLinuxisms
The contents of said wiki page needs to be converted into a separate section of the FreeBSD porters handbook so that porters can find this information easily. When adding these instructions (and possibly examples) to the porters handbook, the source code needs to be correctly formatted and must conform to our documentation source code style guidelines.
A FreeBSD system (in a VirtualBox Virtual Machine) installed on your computer.
