sysroot, right. obviously I don't have AIX so that basically means I can't
build a cross-compiler to it, IIUC. Close as IBTK (aka INVALID)?

Don't you need a sysroot to build a cross compiler in this case?  Try adding
--without-headers --with-newlib if you don't have a sysroot for AIX.  Note
there is nothing AIX specific in building a cross compiler here.

Oh one more thing newlib has not been ported to AIX which is why libc is not
being found.

I found this while trying to add xcoff64 support to libiberty for LTO support
on AIX.

Also fails, but in a different way, if --disable-multilib is removed from the
configure options:

# If this is the top-level multilib, build all the other
# multilibs.
