[RFC][PATCH v8 08/16] Let alternative month names be a copy of regular ones (bug 10871).

[Rafal Luzynski <digitalfreak at lingonborough dot com>]

If alt_mon definition is missing from a locale then let it be
a copy of mon array.  Majority of languages do not need this feature
so let us accept the locale definition file without alt_mon and
provide the same content as mon when software requires alt_mon.

[BZ #10871]
* locale/programs/ld-time.c: alternative month names are a copy of
mon if not provided explicitly.
