The powerpc perf arch port has two issues in the current 3.17-rc
seriers. Undefined dwarf symbols and undefined pr_debug calls.
commit a60335ba [perf tools powerpc: Adjust callchain based on DWARF debug info]
introduces skip-callchain-idx.c, and breaks the perf build.
Unitl fixes get into the mainline kernel, we temporarily fix the issues by
adding a forced linke to -ldw and modifying skip-callchain-idx.c to include
the proper debug files for pr_debug.
