sorry for my poor english :D

first, it's not p->domainname but q->domainname in dcngettext:77.

second, any news about http://www.openwall.com/lists/musl/2016/05/11/81?
strip  '.UTF-8' is important, i think.

irc log:
18:58 < xhe> @dalias: i must found a bug in bindtextdomain(), and also the
improvement about stripping  '.UTF-8' should be merged(my code sucks,
that's for my tests), detailed: http://pastebin.com/3C2APqMH
