If pacman is build against a crypto library other than openssl, it makes no sense to require makepkg to use it.
The only currently considered alternative to openssl is nettle, which has no binary for base64 encode/decode. This means that we could replace the hashing cacluations with nettle-hash, but would require base64 from coreutils. Given makepkg already relies heavily on coreutils, we might as well use all the coreutils hashing binaries too. This patch also improves the checking of required binaries for hashing operations.
