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.
