Note that we skipped R52c because it wouldn't build with clang (thanks to
the "Shave 200 bytes off .text by revisiting string pooling" change).

We also don't need to export variables we inherited --- they're
automatically exported.

hd was only usable from interactive shells. xxd is more functional and usable
from interactive and non-interactive shells.
Change-Id: I294acea221e20ca46b6bc7e8e34906bd5d1b6dad
Needed to make various command-line tools work out of the box, since we
don't have /tmp, which is what they'd naturally fall back to.

gtest won't color its output unless TERM is an xterm, and that seems as
reasonable a default as vt100. More reasonable, in fact. This only fixes
things for login shells, so we still need to fix adb to pass $TERM
through to make yabinc happy...
We can get a better more(1) from toybox, and the aliases seem inappropriate.

This isn't much, but it's a step in the right direction. Really we should
probably generate a trivial Android.mk for building the .c files used by
the mksh equivalent of a configure script.
