Partial fix for YB6495

For YB6495 to be completely fixed, source poky commit for Build Appliance needs to be advanced to this patch after integration.
As such, this is a partial fix.

The following changes since commit 0ed5a13f5f9478e2c22f517fb3504b738422f85c:

qemu: fix qemu-native pkg-config paths

1.9.1

For qemu-native, the pkg-config paths do not include build host paths.
This is an issue for libsdl for example, where SDL is used by qemu, but for qemu-native libsdl-native is not built, but assumed to be provided by the build host. Because pkg-config do not search for libsdl config files on the build host sysroot, the configure stage of qemu-native will fail because it will not find SDL as being installed. Usually, the isssue is masked by a functional sdl-config that will be interogated instead of pkg-config. However, on Build Appliance, sdl-config is deliberately made non-functional, so the issue manifests itself.

The fix will create an extended PKG_CONFIG_PATH, which does include the build host sysroot paths for pkg-config.

Fix for [YP #6495].
