I figured that mediainfo fails to cross build from source, because it
does not find wxWidgets. It invokes wx-config as:
wx-config --host=$DEB_HOST_GNU_TYPE --unicode=yes --static=no base --version
That fails whereas it works after dropping --host:

base --version

I believe that mediainfo's use of --host is reasonable and wx-config
should handle the native --host just fine.
In an IRC discussion Olly Betts figured the matching upstream bug (set
as forwarded above).
In testing this, I found a workaround that makes --host work. If you
copy /usr/lib/powerpc64le-linux-gnu/wx/config/gtk2-unicode-3.0 to
/usr/lib/powerpc64le-linux-gnu/wx/config/powerpc64le-linux-gnu-gtk2-unicode-3.0
and sed 's/^this_host=".*"/this_host="powerpc64le-linux-gnu"/' the new
file, then wx-config works with that --host.
I'm not sure whether that workaround breaks something, but if it
doesn't, I think the packaging could do that and thus unbreak --host.
I'm not convinced enough to set the patch tag though. %-)
