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.
