[Qemu-trivial] [PATCH v3] Makefile: Do not generate files if "configure"

From: Thomas Huth
Subject: [Qemu-trivial] [PATCH v3] Makefile: Do not generate files if "configure" has not been run yet
Date: Thu, 8 Jun 2017 14:59:59 +0200

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).

Signed-off-by: Thomas Huth <address@hidden>
 - 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
