After the first install, I can not install anything if the temp-directory does not exist

[rubyFeedback]

I recently installed void-linux.

I tried to install things such as GCC, but it would fail.

I finally realiased that the reason for this was that I don't have a temp dir.

I modify the default temp dir and it points at /home/Temp for me.

The problem here is that xbps-installer does not notify the user about this.
I found it out by trial and error. My proposal is that the xbps-installer
checks whether that directory exists.

In my case, as I tried to install GCC, xbps-installer complained to me
that it can not install binutils-doc (which is mega-confusing by the way,
why is binutils DOC needed for gcc ... and why do we have to install
gcc; note that manjaro and slackware have gcc available out of the
box. Isn't void-linux supposed to be the linux distribution for geeks?
Why are manjaro and slackware smarter here than void-linux?).

The reason why binutils-doc failed to install was because no temp
directory was available, but I was not notified of this. Instead some
cryptic message showed up e. g. fancypants telling me how it
failed (but not telling my WHY it failed). Please more transparency
for the xbps tools, we new users aren't mega-stupid but could
really need better notifications about that. (The assumption that
tmp is always hardcoded at /tmp is another mistake, but I leave
it up to you guys to figure out why that is so.)
