OK, looks like libpci may well be the culprit. Linking
with the default libtool command line includes the symbol:
$ /bin/sh ../libtool --tag=CC --mode=link gcc -g -fvisibility=hidden
-I/usr/include/libxml2 -fvisibility=hidden -I/usr/include/libxml2
-I/tmp/HWLOC/hwloc-1.3a1r3511/include -no-undefined -version-number
0:0:0 -lxml2 -lz -lm -lpci -o libhwloc.la -rpath /usr/local/lib
topology.lo traversal.lo distances.lo topology-synthetic.lo bind.lo
cpuset.lo misc.lo topology-xml.lo topology-libpci.lo topology-linux.lo
topology-x86.lo

Removing the -lpci results in a library which no longer
references it..

So it's a system library issue - over to you folks! :-)
