High-level dependencies build without system's PATH
The high-level dependencies are now built without having access to the system's PATH. To do this, all the necessary software that we aren't building ourselves are now brought into the installed `bin/' directory using a symbolic link to the corresponding software on the host. To do this, it was also necessary to increase the number of basic/low-level packages that we are building, and add several more (Diffutils and Findutils). With this process in place, we now have a list of the exact software packages that we are not building our selves, enabling easy building of all such dependencies in the future.
