Thank you, Spen. You are right: I've overridden write() and now 
printf outputs to the UART0. But there is an issue and I think it 
might be related to what you said next:

Well, the issue is: the .HEX file generated with GCC is enormous! 
Like 56 kb for a prog that only prints a single formatted variable 
to UART0. The exact same code compiled with "Keil ARM Tools" 
generates a .HEX file that is only 10 kb big.

Do you guys think that such a gigantic .HEX file is because of 
this "statically linking" problem of uclibc? If so, what alternative 
lib do you suggest?
