It's good we do that, but it's bad autoconf does not. Any reasonable
justification?

Well, see how AM_INSTALL_LIBBFD is defined. ;-) There was a discussion
last year...

Why is that so? I am looking at what autoconf does right now and I can
see that $ac_cv_host_alias is set to $ac_cv_build_alias if $host_alias is
empty and $ac_cv_target_alias is set to ac_cv_host_alias if $target_alias
is empty. Why can't the same be done for $host_alias and $target_alias at
the same place? I hope not for the lone reason of differing between
implied and user-specified values -- it can be trivially be done
differently and more explicitly => cleanlier.

That's a reasonable approach for now, but why can't autoconf be fixed
ultimately?

Indeed, but I would prefer to see it done in autoconf so that it need not
be repeated locally elsewhere.
