 I think these two are different things and the real (cross) archiver is
the first one, while the second one seems to be some LTO helper, according
to e.g. this post: https://gcc.gnu.org/ml/gcc-help/2012-03/msg00100.html

 Strange, under Cygwin I have

i.e. I do have both versions.

 This definitely looks wrong, surely the host ranlib can't be used when
cross-compiling.

 I don't have access to the Linux machine on which I've been cross-building
lmi right now, but I'll recheck what happens there when I get it back.
