Hi Ross,

The code was:
PACKAGECONFIG ??= "${@bb.utils.contains('DISTRO_FEATURES', 'bluetooth', 
'${BLUEZ}', '', d)}"
PACKAGECONFIG[bluez4] = "--enable-bluetooth,--disable-bluetooth,bluez4"

BLUEZ is default to bluez5, did you mean that we add a line like:
PACKAGECONFIG[bluez5] = ",,"
or
PACKAGECONFIG[bluez5] = ",--disable-bluetooth,"

But we didn't need such a line, since when PACKAGECONFIG != bluez4, the
--disable-bluetooth will be used.

Maybe we can simply drop this patch ? I made this patch to avoid confusing
the user.
