Ewww, ... - We are doing for so long, I don't recall if there were or
are any directions :)
In a nutshell, it's:
tar xjvf gcc-<gccversion>.tar.bz2
tar xzvr newlib-<newlibversion>.tar.gz
ln -s ../newlib-<newlibversion>/newlib gcc-<gccversion>
mkdir BUILD
cd BUILD
../gcc-<gccversion>/configure --with-newlib .....
i.e. symlink newlib-<version>/newlib into the gcc source tree and then
use gcc's configure (it knows about newlib)
For details (and should you be familiar with rpm specs), cf.
