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.
