https://github.com/void-linux/void-packages/pull/38412

autoconf: update to 2.71.
#### Testing the changes
- I tested the changes in this PR: **YES**

#### Local build testing
- I built this PR locally for my native architecture, x86_64-glibc
- I built this PR locally for these architectures (if supported. mark crossbuilds):
  - armv6l

I have also update autoconf-archive in this pr.

Because this is a critical package I will make sure that all package that depends on autoconf and automake still compile.

There was some changes that might need to add [gtk-doc on hostmakedepends](https://www.mail-archive.com/bug-autoconf@gnu.org/msg04872.html). Separate PRs for the packages will be created and I will reference here.

Compiled all the packages that depend on autoconf and automake `grep -ri autconf` (Yes, I know it has some false negatives).  Thanks @paper42  for that

Packages failing that were failing already (will not fix, probably should be removed in my opinion)

- [ ] gnome-latex
- [ ] libcryptui
