 I'm setting up an Android build environment, and the standalone/android/install-haskell-packages script fails while installing the Magic package. The standalone/android/buildchroot-inchroot package should run `apt-get -y install libmagic-dev` to install this dependency.

+My android builds include neither magic nor concurrent-output (which is
+what's using terminal-size). I don't feel it's worth trying to get
+these features working on androd.
+
+So, I've adjusted install-haskell-packages to disable the flags.
+
+If you are interested in working on the android port, I'd be very excited
+for any help. As you can see, there is much room for improvement in the
+build system for it. (It would be nice to rework it to use stack, rather
+than the current approach, and using stack would automatically disable
+these flags that are not portable.) And of course, there are many other
+parts of the android port that need improvement.
