configure: Silence Xcode warnings about duplicate libraries 

Since Xcode 15, macOS developer tools use a new linker. The new
linker by default warns for duplicate -l options. As this is a
known and expected thing, not to be considered an issue, ask for
the warning to be silenced.

This silences linker warnings like this:

    ld: warning: ignoring duplicate libraries: '-lc++', '-lcrypto', '-lm', '-logg', '-lpthread', '-lssl', '-lvorbis', '-lvpx', '-lz'

The linker can also warn about duplicate -rpath options, and there's
currently no option to silence those warnings.
