==GCC==
Now we change dynamic linker variable for compiling GCC with right version of libraries.

 export LD_LIBRARY_PATH=/tools/lib
 tar xf gcc-4.8.0.tar.bz2
 cd gcc-4.8.0/
 
Go to gcc/config/i386 and edit linux64.h and linux.h.
 
in linux.h
 #define GLIBC_DYNAMIC_LINKER "/tools/lib/ld-linux.so.2"

in linux64.h 
 #define GLIBC_DYNAMIC_LINKER32 "/tools/lib/ld-linux.so.2"
 #define GLIBC_DYNAMIC_LINKER64 "/tools/lib/ld-linux-x86-64.so.2" 

 cd ..
 mkdir gccbuild
 cd gccbuild
 #GCC 4.8.0 is broken with regards to ISL 0.11.1, when its fixed: add --with-isl=/tools
 ../gcc-4.8.0/configure --disable-multilib --with-mpfr=/tools --with-gmp=/tools --with-mpc=/tools --prefix=/tools/ --enable-languages=c,c++
 make -j 8
 make install
 cd ..
 ln -s /tools/bin/gcc /tools/bin/cc
 
We are now ready for next step
