These implement both the old-pre INO64 mknod variations, as well as the
now current INO64 variant. To implement the old stuff, we use some
linker magic to bind to the old versions of these functions.

Where does BSD_HAVE_INO64 come from? I can't find it defined in freebsd git.
You should probably avoid the linker tricks and use direct syscalls of
SYS_freebsd11_mknodat etc.
