OK the problem is here - you seem to be building against a default 
mb-gcc, rather than the uclinux-customised version distributed from my 
website.  For the kernel it doesn't matter, but building user apps you 
need the uclinux-specific mb-ld wrapper script, mb-elf2flt and mb-flthdr 
utilities.

If you have installed the uclinux toolchain, perhaps you have not 
updated your PATH variable to make sure that it is first?

Regards,

John
