gcc-final: hard link TARGET-cc -> TARGET-gcc

Browse Source 
Doing a symlink results in incorrect behavior:

    $ x86_64-buildroot-linux-gnux32-cc
    --version
    ccache: error: execv of [...]/x86_64-buildroot-linux-gnux32-cc.br_real.br_real failed: No such file or directory

    $ x86_64-buildroot-linux-gnux32-gcc --version
    x86_64-buildroot-linux-gnux32-gcc.br_real (Buildroot 2015.11-git-00965-g8d89653-dirty) 5.2.0

[Thomas: use 'ln -f' instead of 'cp -l', as suggested by Arnout.]
