commit 56de31119e040404ace90529b38edd3d7dcbf5aa
from: Omar Polo <op@omarpolo.com>
date: Thu Sep 07 10:01:08 2023 UTC

add configure check for libmd; needed on some OSes for amused-web

On the BSDs the SHA1Init() and friends are part of libc, while on
linux (and maybe other systems as well) we need an implementation
of these function: libmd for example.
