4M sounds like the unstripped size. Make sure you strip the symbols from the
libraries if you are desperate for disk space. Newlib is an implementation of
the C library, but it was intended for use on embedded systems without Linux.
Hence there is no support for the Linux system calls in it.

Another option is to identify the C library functions that you are actually
using and remove the others from the archive. That would be rather tough by
hand. Lineo has a closed source tool called "Lipo" which will do that for you -
there may be a free replacement in the works somewhere.
