These functions were added to glibc 2.38, so we don't even need to check for libbsd. There isn't a strong need to worry about supporting older systems because use of these functions should go away as we rewrite string.c in Rust. And, apparently, they are not held in high regard historically. That's at least 2 reasons to be rid of them.
