You can completely eliminate the need for an ld.so.cache file
if you copy the libraries into /lib on your target with the
exact same names as shown when using 'ldd' on the binaries.

Anyways, if you run 'ldd' and see something like:

    [andersen at slag busybox]$ ldd ./busybox
	    libc.so.6 => /lib/libc.so.6 (0x4001e000)
	    /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

and then make sure you then do something like
    mkdir -p $TARGET/lib
    cp /lib/libc.so.6 $TARGET/lib
    cp /lib/ld-linux.so.2 $TARGET/lib

then things should run just fine without a cache file. 

BTW, I wrote a cross platform ldd for uClibc that reads the needed libraries
and interpreter info directly out of the ELF binaries (instead of trying to
exec the shared lib loader which is what the glibc one does).  It is very nice
for use when cross-compiling and works just fine with glibc, uClibc, whatever
compiled binaries.
