First, you seem to be trying to use the blackfin ld to link your
final application.  Typically, gcc performs the final link so it
can merge in things like crt1.o, which provides the _start
symbol.

Secondly, I am not sure how you are compiling things (since you
omitted that part in your email) but I suspect you are either
using the wrong set of C library header files, or you are in fact
trying to use '_stderr' directly within your code.  Either way,
something is horribly broken, and it is pretty much certain that
broken something is not uClibc.
