Ugh. I totally forgot about the other target libs when I told you
to put that stuff in x-aix43. Sorry.

I think it has to go into the toplevel config directory. You create
mh-aix43, then tweak configure.in. Note the toplevel directory is
not autoconf'd, so you need not run autoconf after tweaking configure.in.
This will probably have to change again if/when binutils is ported to
aix43 since odds are it'll use a different option to achieve the same
