Compiling bdb with clang-16 on aarch64 (hardware) currently fails:
```bash
make -C depends/ bdb CC=clang CXX=clang++
...
checking for mutexes... UNIX/fcntl
configure: WARNING: NO SHARED LATCH IMPLEMENTATION FOUND FOR THIS PLATFORM.
configure: error: Unable to find a mutex implementation
```
Looking at config.log we've got:
```bash
configure:18704: checking for mutexes

Clang-16 changed `-Wimplicit-function-declaration` and `-Wimplicit-int`
warnings into errors, see:
https://releases.llvm.org/16.0.0/tools/clang/docs/ReleaseNotes.html#potentially-breaking-changes.
> The -Wimplicit-function-declaration and -Wimplicit-int warnings now
> default to an error in C99, C11, and C17. As of C2x, support for implicit
> function declarations and implicit int has been removed, and the
> warning options will have no effect. Specifying -Wimplicit-int in
> C89 mode will now issue warnings instead of being a noop.
