what to do about unsupported encodings

pg_get_encoding_from_locale() in chklocale.c reports this when it finds
a locale with an encoding it does not recognize:

ereport(WARNING,
(errmsg("could not determine encoding for locale \"%s\": codeset
is \"%s\"",
ctype, sys),
errdetail("Please report this to <pgsql-bugs(at)postgresql(dot)org>.")));

I guess we don't get many of these reports. But when testing out all
the locales that an OS provides, I can produce tons of warnings like
this, mostly related to legacy encodings of various localities.

Should we maintain a list to the effect of, these are encodings we have
heard about but don't support? Or should we just drop the "please
report this" part? I think the latter was added when we were still
breaking in this code, but it seems to have held up well.
