Adding '-fno-builtin-printf' seems to have solved my problems.  The
built binary is much smaller; on the order of what I expected.  Since it
seems that Newlib is not being linked in, I have to assume that my C
library replacement is being placed in front of it even though I am not
sure how to explicitly say so.  Is there a way to guarantee that this
will always be the case?
