It's important not to think of Newlib as a single monolithic entity.
Your program will include only those bits of Newlib that you need, for
instance the __libc_init_array function.

You might be able to look at the map file to see which newlib objects
are being pulled in, and include just those yourself.  This has
potential to break as you require more of the library, however.
