oneapi: disable use of libirc when building C++

When building with C++ the icx compiler will try to utilize optimized
versions of memset/memcpy that are provided as part of libirc.  However
libirc also has dependencies on things likes getenv/setenv, etc that
are expect in a linux host environment.  So disable use of libirc
via compiler flag -no-intel-lib=libirc.
