Currently, only main programs (like stdbuf) can be disabled at configure time. Helper programs (like libstdbuf.so) do not have a configure option.
Even if you disable stdbuf with the configure option, libstdbuf.so will still be compiled and installed. So delay the parsing of helper programs until after we know the final enable list, and then only build libstdbuf.so when stdbuf is also enabled.
