Daemon build on Android Termux

@cu-kai tried to build daemon-tty on an Android phone using Termux. I tried to debug some issues preventing this.

This allows to build Dæmon engine and Unvanquished (as exe game) on Android. NaCl doesn't work as loaders we use aren't for Android.

Some commits may be merged separately, like the commit supporting TMPDIR environment variable (which would be good to have on Linux anyway). This patch can be merged separately there:

Here is an Unvanquished server running on Android in Termux using exe game:

Why should we add a bunch of kludges to build for Android when it has zero prospects of becoming a usable platform?

@cu-kai was hoping to run daemon-tty on his phone, so I tried to make it work! 😅️

Anyway that's interesting because given the size of patches to make Unvanquished server run with exe on Android is very small, maybe we can run Unvanquished servers on whatever system that looks like Linux enough on whatever architecture that is not that exotic without much larger change if the server runs exe game code.
