Hi,
When I add another name of language, I find field 'la_name' can be
'const char *'. This patch is to constify it.

gdb:

2013-10-28 Yao Qi <yao@codesourcery.com>

* language.c (language_str): Return const char *.
(add_language): Add const to 'language_names'
* language.h (struct language_defn) <la_name>: Add const.
(language_str: Update declaration.
