Your hello world executable is still in ELF format, not the flat binary 
required by uClinux.  You cannot just compile your program with mb-gcc 
and link it using the gcc default processes, you have to explicitly link 
it against the uClinux libraries and also convert it to a flat binary. 
Luckily, it's easy once you know how, just read this page:
