Subject: Make it possible to build the AOSP .config against glibc.

It's possible that we should just pull setprop back out of toybox to
live with getprop in system/core/, but this lets us build the same toybox
configuration for device and host in AOSP.

(Longer term we'd like to use host bionic, but if we enable this we
can start experimenting on the tobyox side before the bionic side is
finished.)
