This doesn't look good: it's not because libselinux is enabled in the
configuration that audit is also enabled.

So your options are:

 * Only enable SELinux support in DBus when both libselinux and audit
   are enabled:

ifeq ($(BR2_PACKAGE_LIBSELINUX)$(BR2_PACKAGE_AUDIT),y)
DBUS_CONF_OPT += --enable-selinux --enable-libaudit
DBUS_DEPENDENCIES += libselinux audit
else
...

   This is the easiest, but it kind of "diverges" from the other
   packages, where enabling the 'libselinux' package was sufficient to
   get SELinux support.

 * Ensure audit is selected when libselinux is available. This could be
   done by adding the following line to dbus/Config.in:

select BR2_PACKAGE_AUDIT if BR2_PACKAGE_LIBSELINUX

   if you add this, then you can keep your dbus.mk change as it is,
   since having BR2_PACKAGE_LIBSELINUX enabled guarantees us that
   BR2_PACKAGE_AUDIT is also enabled.

Best regards,

Thomas
