Does this do what you want if xmlto-native is pulled in from sstate in
an empty tmp?
Hi Ross,

If we don't have it, while runing bitbake world, there was a build
failure for alsa-utils which xmlto enabled.

The alsa-utils invoked xmlto to generate document at his do_compile,
so we have to make sure the above native packages prepared before
xmlto-native.
Shouldn't alsa-utils have a dependency on the docbook pieces it needs as
well as xmlto-native then?

Certainly, these are not build time dependencies of xmlto so something
is not quite right...

Got it, I will add docbook pieces to alsa-utils's dependency, V3 Incoming.

Richard
