Libdw unwinding support is present for every architecture that has a perf_regs.h - perf registers are needed for the initial frame to unwind. Elfutils also supports SPARC, ARC and m68k but there is no support in the Linux kernel for perf registers on these architectures. As the perf supported DWARF unwinding architectures are a subset of the elfutils ones, remove NO_LIBDW_DWARF_UNWIND as there isn't a case of elfutils lacking the support need for perf.
