bin_hook.o and binary.o in makefile.all

[Petr M. <mi...@ph...>]

Somebody has added new file bin_hook.o into makefile.all. This strange file 
does just #include "binary.c". Consequently, makefiles including 
makefile.all fail to link gnuplot because of multiple definitions from 
bin_hook.o and binary.o (e.g. makefile.mgw).

Which one to remove from makefile.all? Or another action to take?
