Subject: [PATCH v2] kunit: fix KconfigParseError handling CC_VERSION_TEXT

Commit 8b59cd81dc5 ("kbuild: ensure full rebuild when the compiler
is updated") added the environment variable CC_VERSION_TEXT,
parse_from_string() doesn't expect a string in value field and this
causes the failure below:

v2:
- maintains CC_VERSION_TEXT in the .config file to ensure full rebuild
when the compiler is updated.

I am pretty there is already a fix out for this issue:

https://patchwork.kernel.org/patch/11592313/

Can you confirm?
