Makefile: fix version.h dependencies
This guarantees the generated version.h will exist before attempting
to compile any c files that include it.
Several source files include the generated version.h, but not all
declare a proper make dependency.
$ grep -r 'version\.h' *.c
compile-i386.c:#include "version.h"
lib.c:#include "version.h"
options.c:#include "version.h"
This allows a sufficiently parallelized make invocation to encounter
ENOENT.
CC compile-i386.o
compile-i386.c:60:21: fatal error: version.h: No such file or directory
compilation terminated.
Makefile:253: recipe for target 'compile-i386.o' failed
make: *** [compile-i386.o] Error 1

[luc.vanoostenryck@gmail.com: modified so that only version.c depends on version.h]
