[PATCH] D134905: [clang] [Driver] Disable default configs via envvar during testing

[Serge Pavlov via Phabricator via cfe-commits]

sepavloff added a comment.

A more flexible way is to implement support for environment variable like `CL` and `_CL` (https://learn.microsoft.com/en-us/cpp/build/reference/cl-environment-variables?view=msvc-170 ). They could be used to deliver `--no-default-config` and would have wide usage than just this one.
