In that case this means we would never be able to verify the pathces
at all, so an argument to not even let the package pass.
No, it means "avoid
running the autotools as part of building and patch
instead to achieve deterministic builds for Fedora".

Why? I see nothing in the design that implies that. In fact autotools
promote autorebuilds when a user modifies the sources of the generated
files.
<sigh/> the autotools are code generators. (upstream) packagers are
supposed to generate and package the generated files, while maintainers
and installers are supposed not to touch them.

If vendors like Red Hat need to modify libtool so that x86_64 is
covered then we need to use the vendor supplied autotools anyway, so
that's not a valid point.
Not this topic again ;) Red Hat hacks libtool to
work-around the bugs
upstream libtool has not been able to fix for years ;)
