    rl78: Don't output CR when LF is encountered in write().
    
    The file libgloss/rl78/write.c currently contains code which outputs
    \r when \n is seen.  The code will then output the \n as well.
    
    This patch removes the bit of code that tests for \n and then outputs
    \r.
    
    I made this change to fix some failures in gdb.base/call-ar-st.exp.  In
    that test, I see two carriage returns followed by a newline.  One CR is
    output by the libgloss code.  The other is output by the terminal driver.
    
    The total list of failures fixed (using the default rl78 multilib) are:
    
    FAIL: gdb.base/call-ar-st.exp: print print_double_array(double_array) (timeout)
    FAIL: gdb.base/call-ar-st.exp: print print_char_array(char_array) (timeout)
    FAIL: gdb.base/call-ar-st.exp: continue to tbreak2 (timeout)
    FAIL: gdb.base/call-ar-st.exp: continuing to tbreak3 (timeout)
    FAIL: gdb.base/call-ar-st.exp: print print_double_array(array_d) (timeout)
    FAIL: gdb.base/call-ar-st.exp: continuing to tbreak4 (timeout)
    FAIL: gdb.base/call-ar-st.exp: print sum_array_print(10, *list1, *list2, *list3, *list4) (timeout)
    FAIL: gdb.base/call-ar-st.exp: print print_small_structs (timeout)
    FAIL: gdb.base/call-ar-st.exp: print print_ten_doubles(123.456, 123.456, -0.12, -1.23, 343434.8, 89.098, 3.14, -5678.12345, -0.11111111, 216.97065) (timeout)
    FAIL: gdb.base/call-ar-st.exp: print print_small_structs from print_long_arg_list (timeout)
    FAIL: gdb.base/call-ar-st.exp: print print_struct_rep(*struct1, *struct2, *struct3) (timeout)
    FAIL: gdb.base/dprintf.exp: call: printf: 1st dprintf (timeout)
    FAIL: gdb.base/dprintf.exp: call: printf: 2nd dprintf (timeout)
    FAIL: gdb.base/interrupt.exp: process is alive (the program exited)
    
    There are no regressions.
