[Qemu-devel] [PATCH:] Fix a make -j race

[Juergen Lock]

Make libuser.a depend on $(GENERATED_HEADERS) too so make -j won't start
building it before the headers exist.  (There may be more bugs like this
but at least this makes (g)make -j4 started from scratch on a quadcore
now always complete here again.)
