gettext: mbrtowc & !mbsinit

[Golubev I. N.]

Version: 0.10.38
System: i586-pc-sco3.2v5.0.2

Some buggy libc's have mbrtowc, but not mbsinit (violate Amendment 1
of ISO C90?).  It appears that this is because mbstate_t value is
never used by mbrtowc (mbstate_t is char, just to shut compiler), so I
pretend that mbsinit always returns true.
