Andreas.

	* sysdeps/unix/sysv/linux/i386/fxstat.c (__fxstat): Use
	INTERNAL_SYSCALL_ERRNO.
	* sysdeps/unix/sysv/linux/i386/fxstatat.c (__fxstatat): Likewise.
	* sysdeps/unix/sysv/linux/i386/lockf64.c (lockf64): Likewise.
	* sysdeps/unix/sysv/linux/i386/lxstat.c (__lxstat): Likewise.
	* sysdeps/unix/sysv/linux/i386/sigaction.c (__libc_sigaction):
	Likewise.
	* sysdeps/unix/sysv/linux/i386/xstat.c (__xstat): Likewise.
