When doing a "make -j10" in the vanilla QEMU source tree (without
running "configure" first), the Makefile currently generates two
files already, qemu-version.h and qemu-options.def. This should not
happen, so let's only build the generated files if config-host.mak
is available (i.e. "configure" has been run already).

v3:
- Check for config-host.mak at the place where we add the dependencies
for $(GENERATED_FILES) instead of adding single dependencies all over
the place
