Update.
	* sysdeps/unix/sysv/linux/seteuid.c (seteuid): Use setresuid32
	syscall directly if possible.  If __ASSUME_SETRESUID_SYSCALL is
	defined drop compatibility code.
	* sysdeps/unix/sysv/linux/setegid.c (setegid): Use setresgid32
	syscall directly if possible.  If __ASSUME_SETRESUID_SYSCALL is
	defined drop compatibility code.
	* sysdeps/unix/sysv/linux/i386/seteuid.c (seteuid): Use
	setresuid32 syscall directly if possible.
	* sysdeps/unix/sysv/linux/i386/setegid.c (setegid): Use
	setresgid32 syscall directly if possible.
