md5deep: support for ARM

[paulhammond]

md5deep currently fails to install on Apple Silicon thanks to an outdated copy of the GNU config scripts in that repo. The issue has been reported upstream. Until they fix it this pull request adds a minimal patch to get the homebrew formula compiling again.

• Have you followed the guidelines for contributing?
• Have you checked that there aren't other open pull requests for the same formula update/change?
• Have you built your formula locally with brew install --build-from-source <formula>, where <formula> is the name of the formula you're submitting?
• Is your test running fine brew test <formula>, where <formula> is the name of the formula you're submitting?
• Does your build pass brew audit --strict <formula> (after doing brew install <formula>)?

brew audit --strict warns that GPL-2.0 is not a valid license which is not related to these changes. Not sure if you'd like that fixed in this PR too?

Not sure if you'd like that fixed in this PR too?

If you could fix it now too, that'd be much appreciated.

The license is a bit complex, I think it's fine to be taken of later on:

This program is divided into two parts, the Tiger code and everything 
else. Let's start with everything else:

Because the vast majority of this program is public domain, the license 
of this project as whole remains public domain. The Tiger code itself is
