patch to prevent cc1 warnings

[Thomas Fitzsimmons <fitzsim at redhat dot com>]

This patch + regenerating newlib configuration files prevents cc1
warnings like:

cc1: warning: changing search order for system directory
"/notnfs/fitzsim/src-newlib-cygwin/i686-pc-cygwin/newlib/targ-include"
cc1: warning:   as it is the same as non-system directory
"../../targ-include"
cc1: warning: changing search order for system directory
"/home/fitzsim/sources/src-gcc-devel/gcc/newlib/libc/include"
cc1: warning:   as it has already been specified as a non-system
directory

cc1: warning: changing search order for system directory
"/home/fitzsim/sources/src-gcc-devel/gcc/winsup/cygwin/include"
cc1: warning:   as it has already been specified as a non-system
directory
cc1: warning: changing search order for system directory
"/home/fitzsim/sources/src-gcc-devel/gcc/winsup/w32api/include"
cc1: warning:   as it has already been specified as a non-system
directory

Previously, these includes were specified as -isystem's in the top-level
configure.in's FLAGS_FOR_TARGET, AND as -I's in newlib_cflags in
newlib's acinclude.m4.  This patch removes the -I flags from
newlib_cflags.

Any objections?

Tom
