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)

There are no regressions.
