    m4_error: fix missing va_end
    
    Most va_end implementations are no-ops, so it probably didn't
    affect many people, but POSIX requires all va_start to be
    matched with va_end for the rare platform where va_end is not
    a no-op.  Detected by Coverity.
    
    * src/m4.c (m4_error, m4_error_at_line): Add missing va_end.
