patches for newlib-1.16.0 and newlib-1.15.0

[Kate Feng]

Hi,

The patches appear confused due to the option flag '-D' that it deserves
to be explained further :

In newlib-1.16.0/newlib/configuire.host or 
newlib-1.15.0/newlib/configuire.host:
for the case of  '*-*-rtems*)' (e.g. line #529) , one can add the 
-DHAVE_BLKSIZE
option to  the 'newlib_cflags' (e.g. line #532) to improve the 
performance the
RTEMS-NFS.

Cheers,
Kate
