I unfortunately can't reproduce the issue, but if you've got some spare
minutes, could you please check whether this patch helps:

These ones are really surprising to me ... *-softmmu/config-devices.mak
should have a proper dependency on hw/Kconfig so they should get
properly rebuild as far as I can tell. Could you please check the
*-softmmu/config-devices.mak.d dependency files whether the dependency
on hw/Kconfig is really there? Hmm, maybe "make" also tries to check the
old dependency to hw/bt/Kconfig first, before regenerating the files ...
not sure how to fix this properly, maybe leave an empty hw/bt/Kconfig
around for a while 'til all build systems have regenerated the
dependency files?
