No, this did not actually work. I was confused. It seems that Libs.private
is ignored.

Instead, I am now applying the following patch:

--- hwloc-1.6.orig/hwloc.pc.in 2012-11-12 06:33:14.000000000 -0500
+++ hwloc-1.6/hwloc.pc.in 2013-01-04 10:09:54.000000000 -0500
@@ -9,4 +9,4 @@
 Requires.private: @HWLOC_REQUIRES@
 Cflags: -I${includedir}
-Libs: -L${libdir} -lhwloc
+Libs: -L${libdir} -lhwloc @HWLOC_LIBS@
 Libs.private: @LIBS@

This seems to work.
