He's right - it's broken.  There's a patch that's in Gentoo and Red Hat,
but it doesn't fix this problem.

There's also this one which I haven't tried:
http://patchwork.ozlabs.org/patch/255486/

You're going to have to either try the patch in the last URL and rebuild
glibc with it, or take the ldconfig from Slackware 14.0 -- works for me:

cd slackware64-14.0/slackware64/l
mkdir Q ; cd Q
tar xf ../glibc-2.15-x86_64-7.txz
cp sbin/ldconfig /sbin/ldconfig-2.15

Go into a dir of ARM shared objects:

prisere [p3] # readelf lib/ld-2.17.so -h|grep Machin
  Machine:                           ARM
prisere [p3] # uname -m
x86_64
prisere [p3] # /sbin/ldconfig-2.15 -r .
prisere [p3] # strings etc/ld.so.cache |head -n5
ld.so-1.7.0
glibc-ld.so.cache1.1G
libz.so.1
/lib/libz.so.1
libuuid.so.1
prisere [p3] #
