On your host, you can type something like:
----
alex@berk:/usr/src/wag54g$ readelf -d 
buildroot/output/target/usr/sbin/ip6tables-multi  | grep Shared
 0x00000001 (NEEDED)                     Shared library: [libip6tc.so.0]
 0x00000001 (NEEDED)                     Shared library: [libxtables.so.4]
 0x00000001 (NEEDED)                     Shared library: [libdl.so.0]
 0x00000001 (NEEDED)                     Shared library: [libm.so.0]
 0x00000001 (NEEDED)                     Shared library: [libc.so.0]

This will list all the libraries that you need installed[1], I'm guessin 
you have missed one.

You can look at the output of 'readelf -a' to try to see what might be 
missing.

Cheers

[1] in addition to the interpreter required (for example 'ld-uClibc') 
        and the main C library being used:
        readelf -l buildroot/output/target/usr/sbin/ip6tables-multi
