configure.ac: fix static build with hwloc 

Retrieve hwloc dependencies through pkg-config to avoid the following
static build failure:

checking for hwloc_get_proc_cpubind in -lhwloc... no
configure: error: can not find required library libhwloc

This build failure is raised because without pkg-config, hwloc
dependencies such as libxml2 are not retrieved:
