## Message

```
glibc: add backwards compatibility for some symbols

- `fcntl` was renamed to `fcntl64` in glibc 2.28 (see #9485)
- `res_{,n}{search,query,querydomain}` became "their own" symbols since
  glibc 2.34: they were prefixed with `__` before.

This PR makes it possible to use `fcntl` with glibc 2.27 or older and
the `res_*` functions with glibc 2.33 or older.

These patches will become redundant with universal-headers and can be
dropped. But we have to do with what we have now.

Closes #9485

```
