Ok. I think it's possible to remote the install: all in favour of
install: but the bug you see here is not in our build system (at least I
believe so).

The issue seems to be that .d files (generated with gcc -MMD option)
still include libxml/ headers in the dependency chain. This looks wrong
to me.

If I generate the .d file using -MD I can see all system includes
(including openais headers from /usr/include/openais), but with -MMD
openais goes away together with all the other system includes. xml2
stuff is still there.

I wonder if gcc is unhappy because xml2-config pulls
in /usr/include/libxml2 and marks that as non system standard path.
