This is a followup on a concern reported by Stephane Carrez on the
GDB mailing list:

I think we shouldn't fail like this because we have some symbols for an
unsupported language. Could we for instance fallback to C for unknown
language symbols.
I looked at set_cu_language in dwarf2read.c. What would be the
consequences of setting cu_language to language_c in these cases:
case DW_LANG_Ada83:
case DW_LANG_Ada95:
case DW_LANG_Cobol74:
case DW_LANG_Cobol85:
case DW_LANG_Pascal83:
case DW_LANG_Modula2:
default:
cu_language = language_unknown;
break;
