Looks like a very odd failure, unfortunately I cannot reproduce with
pyro or master on recipes that use version control or dynamic SRCREV
features. Could you provide some build config info and if possible the
recipe that is generating the error?

If you don't need the pmu-firmware built via the meta-xilinx layer
(e.g. you source it externally or via meta-xilinx-tools), you can
remove the include and that dependency.
