That's not entirely true. The man page specifically says the path in
the man page is an example, so it need not match the arch in use, it can
simply be one or the other with no substitution. For the provider lib
path, it's in a comment, so again it would be possible to use proper
verbage to express that it is a sample and not use substitution. We
might even be able to do something like:

# Modern distros commonly use either /usr/lib or /usr/lib64 for the
# default _libpath. Substitute the correct value below before
# uncommenting
# provider_lib_path _libpath/ibacm
