    [PATCH] newlib: Only call _fputwc_r if ELIX_LEVEL >= 4
    
    (nano-)vfprintf.c is enabled for ELIX_LEVEL >= 1. When _WIDE_ORIENT
    is set, its __sprint_r / __sfputs_r functions unconditionally called
    _fputwc_r which is only in ELEX_LEVEL >= 4. With this commit,
    the _WIDE support in (nano-)vfprintf.c is disabled for ELEX_LEVEL < 4.
