[PATCH] build: Don't use non-posix arguments for build without GNU coreutils

[Zach DeCook]

date will output a date like
2024-06-05T17:06:30EDT

(time zone is different than currently specified)

ln won't create a relative link
(not a big deal because the command gets reran each time)

specifically tested in Alpine Linux, using busybox utils
