    Allow aux_cache_file open()ing to fail silently even in the chroot mode.
    
    The aux_cache fix of bug 11149 introduced a new bug - normally,
    ldconfig -r never cares if the auxiliary cache is not available and
    that is not a fatal problem, however this is not the case in case
    of ldconfig -r when executed as non-root. In that case, ldconfig -r
    fails hard unless var/cache/ldconfig/ exists within the chroot. This
    patch fixes that.

    Fix multiple nss_compat initgroups() bugs
    
    Compat initgroups() is completely broken; the code will always set
    skip_initgroups_dyn to true, so initgroups() will never be actually
    called, but due to the nature of the code, setgrent() won't be called
    either - thus, subsequent invocations of initgroups() will not return
    the NIS group list anymore.
    
    This is a simple patch that makes sure skip_initgroups_dyn is set only
    in case initgroups is not available; it also attempts to handle the
    unavailability of other NSS interfaces better.

    32bit memset-sse2.S fails with uneven cache size
    
    32bit memset-sse2.S assumes cache size is multiple of 128 bytes.  If
    it isn't true, memset-sse2.S will fail.  For example, a processor can
    have 24576 KB L3 cache and 20 cores. That is 2516582 byte per core. Half
    of it is 1258291, which isn't helpful for vector instructions.  This
    patch rounds cache sizes to multiple of 256 bytes and adds "raw" cache
    sizes.
