memchr: Work around bug on Android <= 5.0.
On Windows platforms (excluding Cygwin), @code{setlocale} understands different
locale names, that are not based on ISO 639 language names and ISO 3166 country
names.
+@item
+On Android 4.3, which which doesn't have locales, the @code{setlocale} function
+always fails. The replacement, however, supports only the locale names
+@code{"C"} and @code{"POSIX"}.
