You really need to be using the latest gcc (ie. svn trunk, aka 4.3) before we 
can help you.

gcc also has a uclinux target. You should be using that rather than the 
generic ELF one.

Why on earth do you need to do this? Can't you get the linker to generate PLT 
sequences like we do for normal shared libraries?
