There already are autoconf's --program-prefix, --program-suffix and
--program-transform-name options which can do everything that is needed.
For example, Gentoo uses these configure options to install Emacs' ctags
as (e.g.) "ctags-emacs-28". Exuberant/universal ctags is installed as
"exuberant-ctags". "ctags" is a symlink to one of them and can be
updated by the user.

I tend to agree. From a distro point of view, testing for an installed
ctags binary (with the purpose to avoid file name collisions) is not
helpful. The set of files in the installed image should not depend on
random factors like package installation order.
