I committed a proper fix in
pkgsrc/databases/mariadb55-client/patches/patch-mysys_my_symlink.c

The problem is that Linux considers a -1 file descriptor argument to
openat() as referencing the root of the filesystem. NetBSD sides with
OpenGroup XSH and fails with EBADF in such case, and MariaDB assumed
Linux behavior.

(AT_FDCWD is -100 and not -1 for whoever thought of such a possibility)
