linux-libc-headers-imx (2.6.35.3): add patch to export accept4 syscall

This patch has been backported from 2.6.36 and needs to be included
here, besides the kernel, to properly export the syscall to libc
headers.

+Subject: [PATCH 1/2] ARM: 6329/1: wire up sys_accept4() on ARM
+
+sys_accept4() was added in kernel 2.6.28, but ARM was not updated
+to include it.  The number and types of parameters is such that
+no ARM-specific processing is needed, so wiring up sys_accept4()
+just requires defining __NR_accept4 and adding a direct call in
+the syscall entry table.
+
+Tested with an EABI 2.6.35 kernel and Ulrich Drepper's original
+accept4() test program, modified to define __NR_accept4 for ARM.
+
+Using the updated unistd.h also eliminates a warning then building
+glibc (2.10.2 and newer) about accept4() being unimplemented.
+
+Upstream-Status: Backport [2.6.36]
