[PATCH 01/12] perf tools: Move libdw availability check before arch Makefile

From: Namhyung Kim
Date: Fri Sep 28 2012 - 05:43:03 EST


From: Namhyung Kim <namhyung.kim@xxxxxxx>

Since NO_DWARF is used in arch/$(ARCH)/Makefiles, it should be checked
before including those files. It was moved by mistake during libelf
dependency removal work by me, sorry.
