Grumble grumble.

Sigh.

Fidget.

Grrr...

This is almost certainly the right thing to do. Lemme figure out where
the new edges of this can of worms are.

I know that no external library should ever be REQUIRED by the build.
And I still want the hermetic/selfhosting builds to work with defconfig
toybox, so may wind up adding builtin slow/simple implementations of
more stuff that libraries provide optimized versions of.

But yes, I should apply this. Lemme finish up my pending md5sum changes
first though. (I'm 2/3 of the way through adding -c support.)
