This ldd shows something to be badly broken.  You should _never_ see 
libc.so.6 and ld-uclibc.so.0 linked to the same executable.

Where is uClibc installed to?  What does your Config look like?  Is it stock?
How about your busybox/Makefile and busybox/Config.h?  I don't understand how
you could get /lib/ld-linux.so.2 _and_ libc.so.6 _and_ ld-uclibc.so.0 linked to
your libuClibc-0.9.5.so library.  That is so far beyond amazingly broken, we
almost need a new word to express it.  But I can assure your, this is very
broken.

This is what you should see (in this case, I have _everything_ turned on):
