stubdom: fix errors in newlib

rpm post-build-checks found a few code bugs in newlib, and marks them as
errors. Add another newlib patch and apply it during stubdom build.

I: A function uses a 'return;' statement, but has actually a value
   to return, like an integer ('return 42;') or similar.
W: xen voidreturn ../../../../newlib-1.16.0/libgloss/i386/cygmon-gmon.c:117, 
125, 146, 157, 330

I: Program is using implicit definitions of special functions.
   these functions need to use their correct prototypes to allow
   the lightweight buffer overflow checking to work.
     - Implicit memory/string functions need #include <string.h>.
     - Implicit *printf functions need #include <stdio.h>.
     - Implicit *printf functions need #include <stdio.h>.
     - Implicit *read* functions need #include <unistd.h>.
     - Implicit *recv* functions need #include <sys/socket.h>.
E: xen implicit-fortify-decl 
../../../../newlib-1.16.0/libgloss/i386/cygmon-gmon.c:119

I: Program returns random data in a function
E: xen no-return-in-nonvoid-function 
../../../../newlib-1.16.0/libgloss/i386/cygmon-gmon.c:362
