Looks like a nice cleanup in general.
My only concern was that libelf.h is a "more" public header than libdw.h
and so the macros could in theory clash with other code. But I couldn't
find any other code that uses them except elfutils code itself. And if
there was any then we already exported them through libdw.h anyway. It
does add another explicit dependency between elfutils libdw and elfutils
libelf, but given that libdw already does have some dependencies on
elfutils libelf internals I don't think that matters.
Applied to master.
