Previously, when using compiler wrappers (`--override-compiler`, as is default 
on macOS with SIP on), CC/CXX were set to just `intercept-cc/c++`, which are 
installed to libexec (so a priori not in PATH).

This PR mirrors what's done in `analyze-build`, and sets those to explicit 
paths to `intercept-cc/c++`.
