\url{http://github.com/libtom/libtommath}, if successfully done so.
Intel's C-compiler (ICC) is sufficiently compatible with GCC, at least the newer versions, to replace GCC for building the static and the shared library. Editing the makfiles is not needed, just set the shell variable \texttt{CC} as shown below.

CC=/home/czurnieden/intel/bin/icc make
\end{alltt}
