Can't build Bazel using Intel compiler (1)

Building Bazel on RHEL 6 using commit c1b1eed

In the absence of any documentation about doing this, I've set the paths for the "gcc" fields found in tools/cpp/CROSSTOOL to the fully-qualified path of icpc. Compiling gives:

'''
$ ./compile.sh
INFO: You can skip this first step by providing a path to the bazel binary as second argument:
INFO: ./compile.sh build /path/to/bazel

@mj-harvey Is this still relevant? (Can we move all discussion to #664?)
