If you run 'make dtbs_check' without installing the libyaml package,
the error message "dtc needs libyaml ..." is shown.
This should be checked also for 'make dt_binding_check' because dtc
needs to validate *.example.dts extracted from *.yaml files.
It is missing since commit 4f0e3a57d6eb ("kbuild: Add support for DT
binding schema checks"), but this fix-up is applicable only after commit
e10c4321dc1e ("kbuild: allow to run dt_binding_check and dtbs_check
in a single command").
I gave the Fixes tag to the latter in case somebody is interested in
back-porting this.
