Subject[PATCH] perf tools: Fix feature check for libdw dwarf unwind
When the feature check for libdw dwarf unwind support was added with commit
45757895c7, it required LIBDW_DIR to be set before it would work. However,
commit 0a4f2b6a3ba implies that the libdw unwinder should be auto-detected
from the installed libraries and not require LIBDW_DIR to be set.

The feature check is failing because FEATURE_CHECK_LDFLAGS-libdw-dwarf-unwind
is only being set when LIBDW_DIR is specified. This causes the feature test
to be built without -ldw, which causes it to fail. Fix this by moving the
endif for the LIBDW_DIR check up.
