That should be clear from the documentation at http://gcc.gnu.org/install/ (it's step 6) and http://gcc.gnu.org/wiki/InstallingGCC (it's the last command shown in the example) Also, only "make install" needs to be done as root, there's no reason to use sudo to configure or compile GCC (or most other software).
