When hw/$DIR/Kconfig is changed, the corresponding generated
hw/$DIR/config-devices.mak is not being updated.
Fix this by including all the hw/*/Kconfig files to the prerequisite
names of the rule generating the config-devices.mak files.
Fixes: e0e312f3525a (build: switch to Kconfig)

If OK, I plan to include this fix in the "hw/i386/pc: Split PIIX3
southbridge from i440FX northbridge" pull request.

Why can't we use the simpler wildcard statement:
$(wildcard $(SRC_PATH)/hw/*/Kconfig)
instead of reading the file names from the hw/Kconfig file ?
Regards,
Daniel

You might have uncommited Kconfig files, but this shouldn't be a
problem, make is only interested in checking the modification time of
these files.
Thanks for reviewing, I'll respin.

You can see this tread where Peter reported the failure:
https://lists.gnu.org/archive/html/qemu-devel/2019-11/msg00125.html
How to reproduce:
$ git checkout next_branch
$ make i386-softmmu/all
$ git checkout prev_branch
$ make clean
$ make i386-softmmu/all
# error
$ make print-MINIKCONF_INPUTS
