    Looking closer at what the mentioned patch introduced:
- local sum="$(${integ}sum "$file" | cut -d ' ' -f 1)"
+ local sum="$(openssl dgst -${integ} "$file" | awk '{print $NF}')"
    I'm proposing not to get back to what it has been (which assumed
that there was a md5sum sha128sum, <something-else>sum), but I'm
proposing that for md5 we should use md5sum, which I'm sure it exists
on any UNIX. Or better even, try to see if openssl exists, if not
falling back to md5sum, at least for md5sums...

    This doesn't break anything, and it allows makepkg to work without openssl.

    I understand that `file` tool was introduced to enhance makepkg,
and I'm not proposing to drop it, but instead if `file` does not
exist, to fall-back to file-extension handling.

    Please see that I'm saying everywhere:

    If <something> tool does not exist, switch back, that is fallback,
to some more primitive way of solving things.
