[newlib-cygwin] Use MINSIGSTKSZ and SIGSTKSZ from newlib for Cygwin as well


https://sourceware.org/git/gitweb.cgi?p=newlib-cygwin.git;h=6442e914d9213a6d4fe9d58e9a33bc407e18a2aa

commit 6442e914d9213a6d4fe9d58e9a33bc407e18a2aa
Author: Corinna Vinschen <corinna@vinschen.de>
Date:   Sat Jun 20 19:05:51 2015 +0200

    Use MINSIGSTKSZ and SIGSTKSZ from newlib for Cygwin as well
    
    	* libc/include/sys/signal.h: Move altstack macros completely
    	outside of rtems block.
    
    	* include/cygwin/signal.h: Remove definitions of MINSIGSTKSZ
    	and SIGSTKSZ here.
