If we want to go this route, here's a patch that implements it.


This makes it so we don't override the compiler or flags (other than necessary includes
flags) when building the native module.  So when configuring with CC=clang, the Python
native module gets built with the Python distribution's default compiler, with just the
flags it wants.

Could you check if that works with CC=icc as well?
