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.)

+
+ Provides a slightly less useful output format dictated by
