 Currently, hwloc generates a fatal error if pkg-config is not available.
 It is not available on SuperMUC.  There is a pre-installed version of
 hwloc available, and I was able to make it work by modifying configure.sh
 to comment out references to pkg-config, and re-enable the commented-out
 lines

 {{{
 HWLOC_INC_DIRS="${HWLOC_DIR}/include"
 HWLOC_LIB_DIRS="${HWLOC_DIR}/lib"
 HWLOC_LIBS='hwloc'
 }}}

 Would it be correct to try this if pkg-config is not found, or would this
 lead to hard-to-find errors later on in some situations?  The attached
 patch implements this logic.  OK to apply?
