Subject: [PATCH] fix build without mbstate_t

Commit 41911aac46d69df6a205af59d60f23a418b0e875 tried to fix build
without wchar by checking for the availability of wchar.h however some
toolchains have wchar.h but does not define mbstate_t and mbsrtowcs so
replace HAVE_WCHAR_H by HAVE_MBSRTOWCS

Fixes:
