bug#67754: tags for objc and objcxx

[Alex Ameen]

Hey yeah I'm here, but honestly I need to step down.

I have a kid on the way in a few weeks and have been really inattentive to the libtool work. 

Apologies for the radio silence.

Hi (is there anyone maintaining libtool nowadays? Alex, are you there?) -

I just installed the patch below to Automake, passing the OBJC and
OBJCXX tags to libtool for the respective languages. It would be good if
libtool recognized those tags.
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=67539

The reason to pass them before being recognized by libtool is to
avoid an immediate fatal error, as explained in that bug.
The libtool manual says (line 2930):
    [...] can't infer
    a tag, then it defaults to the configuration for the @code{C} language.

But clearly this is no longer the case, which seems like a good
thing. Thus I suggest replacing that text with something like:
    [...] can't infer
    a tag, then it exits immediately with a fatal error.

Happy hacking,
Karl
