Update.
	* sysdeps/generic/dl-sysdep.c (_dl_sysdep_start): If HAVE_AUX_XID is
	defined don't look whether the AT_*ID values were set.
	If HAVE_AUX_PAGESIZE is defined don't look whether the pagesize is set.
	(_dl_show_auxv): Rewrite to avoid switch statement.
	* sysdeps/unix/sysv/linux/kernel-features.h: Define
	__ASSUME_AT_PAGESIZE for kernel >= 2.4.1.
	* sysdeps/unix/sysv/linux/ldsodefs.h: Define HAVE_AUX_XID.
	Define HAVE_AUX_PAGESIZE if __ASSUME_AT_PAGESIZE is defined.
