Commit Message
This adds a runtime fortification function, __fcntl_2, similar to
__open_2, that checks at runtime whether the actual passed-in command in
fact requires a third argument, and aborts if so.
The abilists have been modified with 'make update-all-abi'.

Compared to v3, now targeting GLIBC_2.39.
You can still drop this patch if you don't want it.
