This means you should have newlib unpacked for making the compiler. You
can't make the newlib without having a compiler, but the compiler needs
to know, what will be in the newlib once it's done (for libgcc I
believe).

Normally it goes the following way.

make binutils
unpack newlib
unpack gcc
configure gcc (--with-headers=<path to the newlib-headers>)
make gcc
configure and make newlib.

Regards,
