Zap toys/Config.in and instead create generated/Config.in from contents of

toys/*.c.  Move relevant info into comment at the top of each toys/*.c.  Also
convert more of Makefile into a thin wrapper around shell scripts that actually
do the work.  (Makefile is only still there for the user interface.)
