diff toys/readlink.c @ 233:d4176f3f3835

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.)
