>From what I see, we need to make utmpx.h, shadow.h, and pty.h optional.

pty.h is minimal: disable telnetd (pending) and part of netcat.

utmpx.h is something I've been wanting an excuse to disable.
It means turning off w, who, and the user count in uptime.
(There's also a lot of stuff in pending that will get turned off.)

shadow.h bites; it means we'll need to disable su, passwd, login, and
(pending) sulogin.
I suppose that the Android authentication system will be completely different.

Since I'm eager to see utmpx made optional, I'll be sending in a compile-time
probe for utmpx shortly. (I have the test written, but have not tried it
or hooked it up.)
And while I'm in the process of mucking around with that, I might as well
add compile probes for shadow.h and pty.h.

There was an old patch queue related to Android support that seems to have
not gotten applied, but large portions of it have been rendered irrelevant.
