Download script attempts to write to ~/mars

[MVittiS]

When invoking the initial step in the "complete toolchain" part of the Installation Guide, the script attempts to copy the downloaded tarballs to ~/mars, which doesn't exist on this machine, nor was it specified in the guide.

$marsdev > make m68k-toolchain-newlib LANGS=c,c++ -j3

It's the default install location, but it looks like I forgot to copy that info into the new install guide after the refactor last week, sorry about that. It can be changed by specifying MARSDEV=/some/where/else

A step that writes to it ran before the step that creates it because I still have to fix parallel building (of the toolchain itself, but gcc and binutils are passed -j).

Current version uses a "work" directory within the repository root instead of doing anything with home, so closing this.
