perf tools: Support static linking with libdw
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. v2: Explicitly check for static linking and only add the dependencies when -static is set. This is to avoid regressions on Arnaldo's system.
