cilacc: static link `intel-openmp,ipp`

[casperdcl]

Some Intel libs exist on PyPI (very useful post-#2145):

• intel-openmp
• ipp
  • ipp-devel
  • ipp-static

However to avoid conflicts with user runtime environments, package managers (conda vs pip), etc, it's best to statically link (that way we can e.g. drop the pip install --no-deps flag introduced in #2145)... but this likely requires updating our licence to include Intel's text.

Alternatively we could try to write code in such a way that it will work regardless of the runtime dynamic library versions (?)
