    inteltool: Allow to override Makefile variables
    
    Allow to override the variables `CC`, `INSTALL`, `PREFIX`,
    `CFLAGS` and `LDFLAGS`. Though append `-lpci -lz` to `LDFLAGS`.
    
    This way for example a different compiler can easily be used.
    
        CC=clang make
    
    As a side note, Clang in contrast to GCC does *not* issue the
    following warnings.
    
        $ clang --version
        Debian clang version 3.2-1~exp6 (tags/RELEASE_32/final) (based on LLVM 3.2)
        Target: i386-pc-linux-gnu
        Thread model: posix
        $ gcc --version
        gcc-4.7.real (Debian 4.7.2-15) 4.7.2
