-# This is an extended/modified qemu.bbclass tailored four our needs:
-#
-# * 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.
