+#
+# * add qemu-native to DEPENDS: we can do that because there is no
+#   introspection/interception delayed qemu usage here
+# * The executable binary is set by absolute path: oe-core's qemu.bbclass
+#   expects it in sysroot. Here we usually run binaries in builddir which are
+#   not yet installed.
+# * A recipe can set an extra library path in 'QEMU_EXTRA_LIBDIR'. This path is
+#   an absolute path.
