This is strange. I just tried building the hwloc tree with prefixing
enabled, I could not find any problem (except one missing symbol that
doesn't matter here, see next commits).

Basically nothing has changed outside of src/topology-xml.c, the above
symbols existed before, they still exist. I don't understand why their
renaming would fail now. However, those were in #ifdef HWLOC_HAVE_XML
before, but this symbol isn't used anymore. Did you rerun autogen ?
