Can this be a weak symbol, so it can be overridden by user code?

If my application causes errors on some version of ALSA, having diagnostic
information going to stderr is inconvenient: I centralize all diagnostics
for bug reporting in a single file, so I don't have to pull teeth from users
to have them copy bits of information from other places.

As long as snd_err_msg() is only called on "unexpected" errors (eg. what
used to be assertion failures), and made a weak symbol, I can redirect it
to my logs.

I currently do this with __assert_fail() and __assert_perror_fail(), and I'd
like to continue to be able to catch all important diagnostic output
automatically.
