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

These are only shown under 32-bit and not 64-bit

$ uname -m

and are going to be fixed in a separate patch.
