Intel compiler - missing proper definitions to use intel linker and librarian (tested with 11.1 but maybe relevant with other versions)

When using the Intel compiler it seems the win32-icc mkspec is missing the proper definitions to use the Intel linker and Librarian.

Below is a patch that corrects this when tested with ICC 11.1 on windows. Without this, Intel compiler specific optimizations can't be used.

ICC 11.1 is not supported but this maybe relevant with other Intel compilers.
