RFA: Andes nds32 port v4 patch

[Joseph S. Myers]

Since Richard looked at the machine description part of the port, I looked 
at the other pieces.  I'm happy with those pieces with the following minor 
changes:

http://gcc.gnu.org/ml/gcc-patches/2013-09/msg00520.html (libgcc): remove 
the .file directive from crtzero.S.  See 
<http://gcc.gnu.org/ml/gcc-patches/2008-07/msg00123.html> for why such 
directives are best avoided.

http://gcc.gnu.org/ml/gcc-patches/2013-09/msg00522.html (documentation): 
use @deftypefn rather than @table @code when documenting built-in 
functions.  In install.texi, say @samp{newlib} and @samp{mculib} instead 
of using '' quotes.
