From: Andi Kleen <a...@linux.intel.com>
The Fedora 22 version of libdw requires a couple of extra libraries
to link. With a dynamic link the dependencies are pulled in automatically,
but this doesn't work for static linking. Add the needed libraries
explicitely to the feature probe and the Makefile.
